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).

Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. 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

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).

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. 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.Synthetic Route of C73H108O12

A comparative study of the application-based properties of hot melt adhesives (HMAs) formulated with different waxes was written by Robertson, Divann;van Reenen, Albert;Duveskog, Heidi;Brady, Fran. And the article was included in International Journal of Adhesion and Adhesives 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:

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).

Lignin modified PBAT composites with enhanced strength based on interfacial dynamic bonds was written by Li, Wenfeng;Huang, Jinhao;Liu, Weifeng;Qiu, Xueqing;Lou, Hongming;Zheng, Lu. And the article was included in Journal of Applied Polymer Science in 2022.Recommanded Product: 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:

Poly(butylene adipate-co-terephthalate) (PBAT) is a type of synthetic biodegradable thermoplastic copolyester with comparable mech. properties to polyethylene, but the application of PBAT is limited by factors such as high cost, short shelf life, poor weather and water resistance. In order to develop PBAT composites with high performance and low cost, lignin-modified PBAT biocomposites with enhanced tensile strength were prepared via in-situ construction of interfacial dynamic bonds. Zinc stearate and epoxy soybean oil were introduced as the interfacial modifiers to construct dynamic bonds between lignin and PBAT, so as to improve the interfacial compatibility. The results demonstrated that the lignin/PBAT biocomposite with interface modifiers reached the maximum tensile strength of 36.7 MPa and an elongation at break of 725.3% at the lignin content of 5 wt%, with the tensile strength achieved 5% improvement on the basis of pure PBAT (34.9 MPa and 717.6%). When the lignin content was increased to 10 wt%, the lignin/PBAT biocomposite with interfacial modifiers still maintained the tensile strength of 35.4 MPa and the elongation at break of 627.8%, which was 82% and 31% higher than that of the directly compounded sample without interfacial modifiers, resp. Even when the content of lignin loading increased to 20 and 30 wt%, the mech. properties of the composites were still significantly improved by adding modifiers. The hydrophobicity of the composite was also improved after in-situ interfacial modification. The strategy demonstrated in this work provides an effective reference for the development of lignin/PBAT composites with high performance but low cost. 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: 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)).

Star polymers with norbornene/1-octene gradient copolymer arms synthesized by an ansa-fluorenylamidodimethyltitanium-[Ph₃C][B(C₆F₅)₄] catalyst system was written by Yuan, Haobo;Kida, Takumitsu;Tanaka, Ryo;Cai, Zhengguo;Nakayama, Yuushou;Kihara, Shin-ichi;Shiono, Takeshi. And the article was included in Polymer in 2022.Product Details of 6683-19-8 This article mentions the following:

Cyclic olefin copolymers (COCs), among which ethylene (E)/norbornene (NB) copolymer have been commercialized, are novel optical plastics but their brittleness narrows their application fields. In this research, star polymers with NB/1-octene (O) gradient copolymer arms and cross-linked cores were synthesized by adding norbornadiene (NBD)/E or 1,11-dodecadiene (DOD) after NB/O copolymerization using a (^tBuNSiMe₂Flu)TiMe₂ (I)-[Ph₃C][B(C₆F₅)₄] catalyst system with 2,6-di-tert-butyl-4-methylphenol-treated tri-n-octylaluminum (Oct₃Al/BHT) as a scavenger. The obtained star polymers possessed the O-rich soft segments close to the core and the NB-rich hard segments in the outer layer. The DOD-cored star polymers had a larger number of arms (15) and a higher star polymer content (68 wt%) than the NBD/E-cored ones (6 and 58 wt%, resp.). The films of the mixtures of the star and the corresponding arm polymers were molded by a melt-pressing procedure. The tensile properties of the films of the DOD-cored star polymer mixtures were significantly improved compared to those of the arm polymers. The Young’s modulus, yield stress, strength, and strain at break were controlled by the NB content, the arm length, and the gradient structure of the arms. These results clarified the novelty of the star-shaped NB/α-olefin copolymers and would expand the application fields of COCs. 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: 6683-19-8Product Details of 6683-19-8).

Exploring the entangled state and molecular weight of UHMWPE on the microstructure and mechanical properties of HDPE/UHMWPE blends was written by Tao, Gan;Chen, Yuming;Mu, Jingshan;Zhang, Letian;Ye, Chunlin;Li, Wei. And the article was included in Journal of Applied Polymer Science in 2021.HPLC of Formula: 6683-19-8 This article mentions the following:

Three types of ultra-high mol. weight polyethylene (UHMWPE) with different entangled state and mol. weight were blended with high-d. polyethylene (HDPE) matrix by melt blending. Rheol., 2D-SAXS, 2D-WAXD, DSC, and mech. tests were used to study the evolution and difference of microstructure and mech. properties of the blends. The addition of weakly entangled UHMWPE enhanced the chain diffusion and chain orientation ability under a specific flow field. Thus, the rheol. properties and mech. properties of the blends were improved with the mix of weakly entangled UHMWPE. The mech. properties enhancement effect of HDPE/UHMWPE blends with weakly entangled UHMWPE was owing to the shish-kebab structure formed in the injection molding process. The mol. chains of UHMWPE with a low degree of entanglement and high mol. weight increased the lamella size and crystallinity of the blends during processing. This leads to the formation of more oriented shish structures and more kebab lamella. Besides, the mol. chains of weakly entangled UHMWPE were better interlocked and intertwined with other polyethylene chains in the amorphous region, acting as the tie mols., significantly improving the impact resistance. 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: 6683-19-8HPLC of Formula: 6683-19-8).

This study presented a universal LC-MS/MS method for trace anal. of multiple synthetic phenolic antioxidants (SPAs) in foods by complementary use of electrospray ionization (ESI) and atm. pressure chem. ionization (APCI). The analytes included not only the well-known BHT and BHA but also 18 high mol. weight SPAs. The method utilized APCI to achieve sensitive anal. of BHT, Irganox 1010, Irganox 330, and Irganox 3125 based on the finding that APCI significantly improved the sensitivity of these weakly acidic or slightly polar SPAs, and utilized ESI to obtain sensitive anal. of other SPAs. Addnl., the method avoided background contamination by using effective measures including installation of a trapping column in the LC system. Method performance assessment showed satisfactory sensitivity, linearity, accuracy, and precision for anal. of SPAs in vegetable oil, milk powder, and baby fruit puree. Method application revealed widespread contamination of foods with BHT, Irganox 1010, and Irganox 1076.
