Effect of rare earth nucleating agent on supercritical CO₂ foaming behavior of block copolymerized polypropylene was written by Zhang, Yun;He, Yadong;Xin, Chunling;Su, Yanbin. And the article was included in Cellular Polymers in 2022.Reference of 6683-19-8 This article mentions the following:

The rare earth nucleating agent was used to modify block copolymerized polypropylene (PPB) in foaming process. The results show that the crystallization of PPB and the melting temperature of β-crystal increased gradually with increased β-crystal nucleating agent content. The total crystallinity decreased with amount of addition increasing, and the relative content of β-crystal increased first and then decreased. When β-crystal nucleating agent content was 0.4 wt%, the relative β-crystal content reached the maximum value of 95.27%, and the final crystal grain refinement significantly. The addition of rare earth β-crystal nucleating agent has a good effect on improving the uniformity of foam cells. Under the same content of β-crystal nucleating agent and pressure, the average cell diameter and expansion ratio increased with the saturation temperature increasing. After the foaming temperature reaches 155°C, the expansion ratio began to decrease, which was also consistent with the changed trend of relative β-crystal content. At the same content of temperature and relative β-crystal, as the foaming pressure increased, the cell diameter decreased gradually, and the expansion ratio increased first, and then decreased. In the experiment, the researchers used many compounds, for example, 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8Reference of 6683-19-8).

Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Reference of 6683-19-8

Rheological properties of UHMWPE/HDPE blend gels and morphology and mechanical properties of gel-spun fibers was written by Yang, Wenxiao;Bin, Yuezhen;Wang, Hai;Ge, Zhonghui. And the article was included in Polymer Engineering & Science in 2021.Application In Synthesis of 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) This article mentions the following:

To produce polyethylene (PE) fibers with relatively high tensile strength but low cost, ultra-high-mol.-weight polyethylene (UHMWPE)/high-d. polyethylene (HDPE) (UH) blend gels were prepared from paraffin oil and further fabricated into UH blend fibers by gel spinning. This research focused on the rheol. properties of UH blend gels with high solid contents (SCs) ranging from 25 to 100 g/L, as well as morphol. and mech. properties of resultant gel-spun UH blend fibers. The rheol. measurements indicated that the apparent viscosity, shear storage, and loss moduli of the UH blend gels were not markedly increased compared with those of the UHMWPE gel with much less SC. No obvious solid-liquid phase separation occurred in UH blend gels at a temperature above the sol-gel transition temperature UH blend fibers were prepared by drawing as-spun fibers (draw ratio [λ] = 3) at 110°C to λ = 15, 45, 60, and 80, resp. The orientation degree of fibril structure in UH blend fibers increased with increasing λ but the length of fibrils (L_fibril) showed a complex change. The L_fibril of UH blend fibers became larger due to chain arrangement in company with the transformation of the kebab structure to the extended shish structure when the λ was less than 45 but decreased during further elongation (λ = 60 and 80) because of fibril breakage and recrystallization The change in morphol. behavior led to the corresponding change in mech. properties of resultant gel-spun UH blend fibers. The tensile strength of gel-spun UH55-45 blend fiber (UHMWPE/HDPE = 5/5 and λ = 45) reached 15.6 cN/dtex, which could fulfill the requirement of mech. properties in common application. In the experiment, the researchers used many compounds, for example, 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8Application In Synthesis of 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate)).

Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Application In Synthesis of 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate)

Synthesis and characterization of poly(hexamethylene 2,6-naphthalate)-block-poly(tetrahydrofuran) copolymers with shape memory effect was written by Walkowiak, Konrad;Irska, Izabela;Paszkiewicz, Sandra. And the article was included in Materials Research Bulletin in 2022.Recommanded Product: 6683-19-8 This article mentions the following:

Shape memory polymers (SMPs) are able to return to their previous shape after deformation under certain conditions. Several block copolymers can exhibit shape memory behavior. The blocks in copolymers are usually immiscible, which leads to phase separation into rigid and flexible segments. For that reason, these materials combine the mech. properties of elastomers with the processing properties of thermoplastic. Thus, a poly(hexamethylene 2,6-naphthalate) (PHN) and a series of poly(hexamethylene 2,6-naphthalate)-block-poly(tetrahydrofuran) (PHN-b-N-pTHF) copolymers were synthesized via melt polycondensation. The content of the N-pTHF flexible segment varied from 15 to 50 weight%. The materials were characterized with the use of Fourier transformed IR spectroscopy, differential scanning calorimetry, dynamic mech. thermal anal., X-ray diffraction anal., the tensile tests (static and cyclic), and the cyclic thermo-mech. anal. The PHN-b-N-pTHF 50/50 was proved to be a promising thermoplastic shape memory polymer (SMP). In the experiment, the researchers used many compounds, for example, 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8Recommanded Product: 6683-19-8).

Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Recommanded Product: 6683-19-8

Investigations on the influence of multiple extrusion on the degradation of polyolefins was written by Schweighuber, Andrea;Felgel-Farnholz, Alexander;Boegl, Thomas;Fischer, Joerg;Buchberger, Wolfgang. And the article was included in Polymer Degradation and Stability in 2021.Electric Literature of C73H108O12 This article mentions the following:

The importance of mech. recycling of polymers has increased within the last decades, especially due to numerous regulations of governments all over the world. Hereby recycling quotas are enforced to pave the way towards a closed loop recycling. During its lifetime, polymers are exposed to multiple environmental factors, which can already induce degradation However, a major factor that needs to be taken into account is the increased thermo-mech. stress during the recycling process, which may have significant impact on the quality of recyclates as well. In the present work, polyolefins (high-d. polyethylene and polypropylene) were artificially exposed to stress by continuous extrusion at varying speeds and absence or presence of stabilizers to analyze the extent to which the recycling contributes to degradation processes. These samples were analyzed for low-mol.-weight stress markers by thermodesorption gas chromatog. and by high-performance liquid chromatog. (both coupled to mass spectrometric detection). Depending on the extent of stress, the occurrence of odd-numbered linear alkane chains was revealed in polyethylene samples, and of oxidized branched alkanes in polypropylene samples. Correlations with mol. weight (determined by high temperature gel permeation chromatog.) and with decreasing concentrations of stabilizers could be demonstrated. In the experiment, the researchers used many compounds, for example, 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8Electric Literature of C73H108O12).

Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Electric Literature of C73H108O12

Chemical analysis of polymer degradation was written by Mizukado, Junji;Miura, Makiko;Kitada, Yukio. And the article was included in Seikei Kako in 2021.Reference of 6683-19-8 This article mentions the following:

Deterioration due to heat of PP, which is discussed in this paper, especially when it is deteriorated by accelerated deterioration test, is affected by the structure of PP itself, but it is greatly affected by additives such as antioxidants and Many, the internal cause is mainly the type and concentration of the antioxidant, and the external cause is heat. However, when analyzing the deterioration of market-recovered products, it is necessary to consider various possibilities including the internal cause because the external cause is not clear. In addition, since the case where durability depends on antioxidants often applies to other polymers, the author like to consider this PP as one subject. In the experiment, the researchers used many compounds, for example, 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8Reference of 6683-19-8).

NMR used to study the side-reactions between peroxides and antioxidants during the reactive extrusion process of the impact polypropylene was written by Li, Chunfa;Huang, Ting;Bao, Yubin;Chen, Zhe;Lin, Guangxin. And the article was included in Magnetic Resonance Letters in 2022.Synthetic Route of C73H108O12 This article mentions the following:

Side reaction pathways are observed to occur between antioxidants and peroxide during the processing of multiple resin grades mediated by controlled peroxide-induced degradation of impact polypropylene. In the present work, the reaction mechanism and main byproducts between antioxidants and peroxides were investigated. The results demonstrate that peroxides greatly accelerate the decomposition reactions, and the free radicals formed from peroxide decomposition react with, for example, the antioxidant AO 1010 to produce dehydrogenation of Ph propionic unit(s) at the α position (cinnamic acid ester moiety), which generates a conjugated system leading to the increased color of the product. It is the first time to confirm the existence of cinnamic acid group and report its NMR data. Further, this work confirms the dehydrogenation mechanism by comparison with different sterically hindered phenolic antioxidants. It also systematically summarizes the oxidation and degradation mechanism of AO 168 and AO 1010 under air and peroxide environments, resp. Based on present study, clear guidelines are obtained to improve the quality of polymeric products, especially the appearance and stability, during product development. In the experiment, the researchers used many compounds, for example, 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8Synthetic Route of C73H108O12).

In this study, three chem. similar but morphol. different high melting hydrocarbon waxes having similar DSC peak melting temperatures were analyzed, and the influence of their mol. architectures on hot melt adhesive (HMA) performance, was evaluated. Selected waxes included each of the following types: Fischer Tropsch wax (FT), byproduct polyethylene wax (BPPE) and first intention polyethylene wax (FIPE). Both, ethylene-co-vinyl acetate (EVA) and metallocene catalyzed polyethylene (mPE) based HMAs were formulated. The high chain linearity of FT wax resulted in faster crystallization and faster adhesive set times as well as higher peel adhesion, shear adhesion and IOPP heat resistance temperatures Wax viscosities were in direct correlation with resultant HMA viscosities. EVA HMAs had longer set times and were more prone to thermal degradation upon prolonged exposure to elevated temperatures and was most pronounced for FIPE wax. Average traction force was dependent on the open time and wax/polymer combination with FT showing a smaller open time window for both EVA and mPE based HMAs. In the experiment, the researchers used many compounds, for example, 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8Application In Synthesis of 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate)).

Markedly improved photo-oxidation stability of α form isotactic polypropylene with nodular morphology was written by Wu, Hao;Zhao, Ying;Su, Lili;Wang, Kezhi;Dong, Xia;Wang, Dujin. And the article was included in Polymer Degradation and Stability in 2021.Category: esters-buliding-blocks This article mentions the following:

Photo-oxidation degradation behaviors of isotactic polypropylene (iPP) films with different crystalline morphol. were investigated by artificially accelerated aging test. The α form iPP with nodular morphol. was obtained by quenching the melt and subsequent annealing process, and its photo-oxidation degradation behavior was compared with that of the melt-crystallized α form iPP sample. Fourier transform IR spectroscopy, gel permeation chromatog., differential scanning calorimetry, X-ray scattering, dynamic mech. anal. and at. force microscopy were utilized to characterize the microstructural variations of these two kinds of iPP films during photo-oxidation degradation process. The results showed that iPP film of nodular morphol. exhibits improved photo-oxidation stability compared with that of lamellar and spherulitic structure. UV-Vis spectra and O₂ diffusivity test of unexposed and aged samples demonstrated that the iPP film of nodular morphol. has higher transparency and lower O₂ diffusivity than that of lamellar morphol. Combining the microstructural anal. and surface morphol. observation, the improved photo-oxidation stability of “nodular” iPP was correlated with its higher UV light transparency, lower O₂ diffusion coefficient as well as the slower segmental mobility in the amorphous phase. In the experiment, the researchers used many compounds, for example, 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8Category: esters-buliding-blocks).

Pelletizing ultra-high molecular weight polyethylene (UHMWPE) powders with a novel tapered die and addition of high density polyethylene (HDPE): Processing, morphology, and properties was written by Yang, Huaguang;Yilmaz, Galip;Jiang, Jing;Xie, Jun;Langstraat, Thomas;Chu, Raymond;van Es, Martin;Garg, Priya;Turng, Lih-Sheng. And the article was included in Polymer in 2022.Related Products of 6683-19-8 This article mentions the following:

The extremely high mol. weight and mol. entanglement have rendered ultra-high mol. weight polyethylene (UHMWPE) superior properties. However, poor inter-particle diffusion makes it difficult to pelletize UHMWPE powders for easy processing/handling. A novel tapered die with air cooling was proposed to pelletize UHMWPE and a UHMWPE blend with 5 weight% high-d. polyethylene (HDPE) for compression molding and material characterization. The tensile strength of samples prepared with the tapered die outperformed those by the regular die or from virgin powders. The addition of HDPE further improved the tensile strength. Fourier transform IR spectroscopy (FTIR) revealed little chain scission and the lowest amount of oxidation from the tapered die. Intrinsic viscosity (IV) measurements confirmed the negligible chain scission and showed an increment in IV for the UHMWPE/HDPE blend. Multi-angle light scattering with size-exclusion chromatog. (SEC-MALS) indicated no change in the UHMWPE mol. weight distribution, but some crosslinking in the blend. Polarized optical microscopy (POM) showed that the HDPE and extrusion led to a finer UHMWPE domain size and better fusion between UHMWPE and HDPE. The combined effect of enhanced mol. chain diffusion, improved consolidation, and lower oxidation using the tapered die led to 40% improvement of tensile strength for the UHMWPE/HDPE blend. In the experiment, the researchers used many compounds, for example, 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8Related Products of 6683-19-8).

Development of a nano-modified glassy carbon electrode for the determination of 2,6-diaminotoluene (TDA) was written by Buyuktas, Duygu;Ghaani, Masoud;Rovera, Cesare;Olsson, Richard T.;Korel, Figen;Farris, Stefano. And the article was included in Food Packaging and Shelf Life in 2021.SDS of cas: 6683-19-8 This article mentions the following:

The objective of this study was to improve the overall performance of a glassy carbon electrode (GCE) for the detection of 2,6-diaminotoluene (TDA), a possibly carcinogenic primary aromatic amines (PAAs) that poses a serious risk for the consumer′ health because they can transfer from multilayer food packages including adhesives based on aromatic polyurethane (PU) systems, to the food. The modification of the electrode surface was made by means of multi-walled carbon nanotubes (MWCNTs) and mesoporous carbon nanoparticles (MCNs). The MWCNTs-MCNs/GCE allowed achieving the best performance in terms of sensitivity, as revealed by cyclic voltammetry – CV, with an oxidation peak of 20.95 μA over 0.079 μA of the bare GCE. The pH of the medium influenced the oxidation of 2,6-TDA, with highest sensitivity at pH ∼7. Amperometry experiments led to an estimated detection limit of 0.129 μM, and three linear ranges were obtained for 2,6-TDA: 0.53-11.37 μM, 11.37-229.36 μM, and 229.36-2326.60 μM. Chronoamperometry experiments combined with Cottrell′s theory allowed estimating a diffusion coefficient of 2,6-TDA of 1.34 x 10^-4 cm²s^-1. The number of electrons (n∼1) involved in the catalytic oxidation of 2,6-TDA was determined according to the Laviron′s theory. Real sample tests demonstrated that the modification of the sensor using nanoparticls allowed to obtain a highly sensitive and selective sensor, which can possibly used as an alternative anal. device for the rapid, easy, and reliable determination of 2,6-TDA. In the experiment, the researchers used many compounds, for example, 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8SDS of cas: 6683-19-8).
