And the article contained the following:

Unimol. amphiphilic nanoreactors with a poly(4-vinyl-N-methylpyridinium iodide) (P4VPMe+I-) polycationic outer shell and two different architectures (core-crosslinked micelles, CCM, and nanogels, NG), with narrow size distributions around 130-150 nm in diameter, were synthesized by RAFT polymerization from an R0-4VPMe+I-140-b-S50-SC(S)SPr macroRAFT agent by either chain extension with a long (300 monomer units) hydrophobic polystyrene-based block followed by crosslinking with diethylene glycol dimethacrylate (DEGDMA) for the CCM particles, or by simultaneous chain extension and crosslinking for the NG particles. A core-anchored triphenylphosphine (TPP) ligand functionality was introduced by using 4-diphenylphosphinostyrene (DPPS) as a comonomer (5-20% mol mol-1) in the chain extension (for CCM) or chain extension/crosslinking (for NG) step. The products were directly obtained as stable colloidal dispersions in water (latexes). After loading with [RhCl(COD)]2 to yield [RhCl(COD)(TPP@CCM)] or [RhCl(COD)(TPP@NG)], resp., the polymers were used as polymeric nanoreactors in Rh-catalyzed aqueous biphasic hydrogenation of the model substrates styrene and 1-octene, either neat (for styrene) or in an organic solvent (toluene or 1-nonanol). All hydrogenations were rapid (TOF up to 300 h-1) at 25°C and 20 bar of H2 pressure, the biphasic mixture rapidly decanted at the end of the reaction (<2 min), the Rh loss was negligible (<0.1 ppm in the recovered organic phase), and the catalyst phase could be recycled 10 times without significant loss of catalytic activity. The experimental process involved the reaction of Oxybis(ethane-2,1-diyl) bis(2-methylacrylate)(cas: 2358-84-1).Related Products of 2358-84-1

And the article contained the following:

Scaling behavior relating the synthesis conditions with swelling degree, preparation concentration and crosslinking d. of multifunctional ternary-gels consisting of 2-(dimethylamino)ethyl methacrylate (DMAEMA), hydroxypropyl methacrylate (HPMA) and glycidyl methacrylate (GMA) is reported. Swelling is controlled by DMAEMA portion of terpolymers and DMAEMA-rich gels tended to swell more than GMA-rich gels and increase in GMA increase polymer-solvent interaction parameter, χ Critical conditions required for terpolymers to show phase transition are calculated as χ1=0.4993 and χ2=0.2959. Dependence of swelling degree ΦVon gel preparation concentration ν20 as a function of solvent quality is examined Good solvent prediction of φVâ‰?(N Cν20)0.29 indicates a crossover between entanglement-dominated case and strongly cross-linked case corresponding to low and moderate degrees of swelling. Swelling of ternary-gels in different solvents shows that cyclohexanol is a good solvent and solubility parameter is 23.7 (MPa)1/2. Addition of hydrophobic GMA leads to a significant increase in stiffness of terpolymer gels. Increase in elastic modulus as-prepared state is not monotonic and can be controlled by adjusting DMAEMA/GMA ratio since tertiary amine groups triggers cascading epoxy ring-opening reaction. Reduced modulus Gr decreased with increasing swelling degree and scaling relation between modulus and swelling is found as Gr â‰?(ΦV)-0.66 which indicates that ternary-hydrogels, limited to weak stretching regime, obey Gaussian statistics.

The scaling laws relating the preparation conditions to the swelling degree, reduced modulus and effective crosslinking d. of poly(diethylaminoethyl methacrylate-co-hydroxyethyl methacrylate-co-2-acrylamido-2-methyl-propanesulfonic acid), henceforth designated as PDHA, gels prepared by radical crosslinking copolymerization in a solvent mixture were reported. Charge-balanced terpolymer PDHA hydrogels and cryogels (PDHA-Hgs and Cgs) were prepared in different monomer feed compositions The swelling dependence of the reduced modulus was described by a power law relationship Gr â‰?(φv)mwith an exponent of m = -0.30 at low swelling degree, while in the high swelling region the scaling becomes 0.21, indicating the finite extensibility of the network chains. The scaling exponent for the swelling degree and terpolymer composition, φv â‰?(Nν2)m, was found to be -0.13, indicating the increasing extent of the topol. constraints arising from the trapped entanglements. By combining elasticity and swelling results, the scaling relationship between the apparent crosslink d. and HEMA content used in the terpolymer feed was obtained as a cubic polynomial of the mol% of HEMA. In the HEMA-rich terpolymer PDHA Hgs and Cgs, the swelling degree was possibly controlled by the HEMA part of the terpolymer network, while the presence of DEAEM units in the network triggered the thermoresponsive swelling behavior. The dependence of interaction parameter χ on the volume fraction of the crosslinked terpolymer network in the swollen gel ν2 was evaluated and the results revealed extremely strong concentration dependence of χ for all terpolymer samples. Because of their inherent properties, the resulting terpolymer gels might contribute to the improvement of the loading capacity of polymers used in anticancer drug delivery systems.

And the article contained the following:

Cryogels with ion-, and solvent-responsiveness have been designed by cryogelation of 2-(diethylamino)ethyl methacrylate (DEAEMA) as weakly cationic monomer, hydroxyethyl methacrylate as neutral comonomer and 2-acrylamido-2-methyl-1-propanesulfonic acid as anionic termonomer in ethanol-water mixture (50:50 volume/volume), which had been proved to offer a good miscibility of monomers. Influence of composition of terpolymer and polymerization temperature on the properties of terpolymer cryogels (Cgels) and hydrogels (Hgels) were evaluated by swelling kinetics, and response against rapid ionic strength change. Swelling of terpolymer networks in the form of Cgel and Hgel decreased with increase in the size of ions present in swelling medium and followed the order of swelling behavior Cl- > Br- > I-. Terpolymer alcogels exhibited salting-out behavior in the presence of Cl- and Br- ions, while “salting-in” behavior was observed in KI solutions of high concentrations Sensitivity sequence of terpolymer alcogels to mono- and di-valent cations with a common anion (SO42-) on swelling was Na+ > K+ > Mg2+> Zn2+. Swelling data agree well with second-order kinetic model and with increasing amount of DEAEMA in terpolymer feed, diffusion mechanism changed from non-Fickian type to Fickian diffusion. In ionic environments, the salt-sensitivity and excellent water absorption/retention capability give this intelligentized terpolymer gels wide potential applications.

Khodeir, Miriam; Antoun, Sayed; van Ruymbeke, Evelyne; Gohy, Jean-Francois published an article in 2020, the title of the article was Temperature and Redox-Responsive Hydrogels Based on Nitroxide Radicals and Oligoethyleneglycol Methacrylate.Application In Synthesis of Oxybis(ethane-2,1-diyl) bis(2-methylacrylate) And the article contains the following content:

A temperature and redox-responsive polymer hydrogel is constructed by randomly incorporating 2,2,6,6-tetramethyl-1-piperidinyloxy-methacrylate (TEMPO) stable nitroxide radicals and oligoethyleneglycol methacrylate (OEGMA) groups in a polymer network. TEMPO can be reversibly oxidized into an oxoammonium cation (TEMPO+) providing the redox-responsive properties while the lower critical solubility temperature (LCST) of OEGMA results in temperature-responsive properties. Since a rather low amount of di(ethylene glycol) dimethacrylate (OEGMA2) is used to chem. crosslink the polymer network, the accordingly formed hydrogels obtained after swelling with water consist of microgel particles with entangled polymer chains that are not chem. crosslinked. By varying the amount of TEMPO in the polymer network, it is demonstrated that the radical form of TEMPO aggregates into hydrophobic domains acting as phys. crosslinking nodes in the hydrogels and further increasing the cohesion between microgel particles. Increasing the temperature results in two opposite effects on the solubility of TEMPO and OEGMA units. The oxidation of TEMPO into TEMPO+ also results in a deep change in the hydrogel properties since TEMPO+ units are essentially hydrophilic and do not aggregate into phys. crosslinking nodes.

To evaluate the scaling parameters of weakly cationic crosslinked network structures, poly(dialkylaminoethyl methacrylate)-based hydrogels were synthesized via free-radical crosslinking in aqueous solution varying systematically concentration of pregel solution Based on the gel-preparation concentration, variation in structural properties, effective crosslinking d., average mol. weight of polymer chains, and thermodn. parameters from combined swelling and elasticity results were discussed using the scaling theory to predict various exponent identities. The concentration dependence of compressive elastic modulus as-prepared state was described by a power-law relation G0â‰?ν20)m with the exponent of m = 3.55 indicating the importance of the trapped entanglements. Two structural characteristics, the network chain length N and the average mol. weight of polymer chains have inverse dependence on the gel-preparation concentration in the matrix, while the compressive moduli and effective crosslinking d. show completely direct dependence. Exptl. determined N values of PDMAEMA hydrogels first decrease with increasing ν20 up to 0.2972 and the dependence of N on the gel-preparation concentration gives the relation N≈X-1(ν20)n with a scaling parameter n = -1.80, which coincides with the prediction of scaling theory. Acceptable agreement was found between the estimate of crosslink d. fluctuations deduced from mech. measurements and the results derived from independent swelling observations. © 2019 Wiley Periodicals, Inc.

On May 31, 2022, Bozbay, Rabia; Orakdogen, Nermin published an article.Name: Oxybis(ethane-2,1-diyl) bis(2-methylacrylate) The title of the article was Temperature-regulated elasticity and multifunctionality in n-alkyl methacrylate ester-based ternary gels: optimizing adsorption and pH/temperature dual sensitivity. And the article contained the following:

An attempt was made to correlate the gelation temperature with elasticity and pH/temperature dual sensitivity of n-alkyl methacrylate ester-based cationic gels. Ternary gels were prepared by free-radical crosslinking of HPMA, DMAEMA, and GMA in water at fixed monomer and crosslinker concentrations, while gel preparation temperature Tprep was varied from – 18 to 60°C. The structure and phys. properties of ternary gels were fully characterized using thermal gravimetric anal., Fourier transform IR spectroscopy, and X-ray diffraction. Tprep has been shown to be an effective independent variable to adjust both macroscopic and microscopic properties of ternary gels as desired. Gelation temperature dependence of swelling and compressive elasticity was investigated. Ternary gels synthesized at 5°C showed maximum swelling capacity. The equilibrium swelling ratio increased first slightly up to 5°C and then decreased continuously with increasing Tprep. This trend indicated that swelling is influenced by properties of both crosslinking region and the main constituent amorphous region. In swollen state, elastic modulus of gels changed from 0.9 to 108 kPa and increased 120 times as Tprep decreased from 60 to – 18°C. Terpolymer gels showed pH-sensitive swelling characteristic of cationic DMAEMA monomer and exhibited high swelling ratio in acidic solutions induced by electrostatic repulsion between quaternary amine groups. The swelling ratio decreased due to hydrophobic effect of the alkyls when environmental pH is higher than 7.7. Regardless of Tprep, the gels gradually contracted as swelling temperature increased from 25 to 75°C. Flory-Huggins interaction parameter χ ranged from 0.4005 to 0.5358 and increased with the degree of intermol. hydrophobic interactions. The effectiveness of ternary gels for removing methyl orange from aqueous solution was tested, and the results showed that the gels prepared under low-temperature conditions were promising for removing anionic dyes. The adsorption was spontaneous and found to be a multistep process with surface adsorption followed by intraparticle diffusion. This knowledge will aid the future design of n-alkyl methacrylate ester-based ternary gels as an effective adsorbent for dye removal from wastewater and pharmaceutical preparations The experimental process involved the reaction of Oxybis(ethane-2,1-diyl) bis(2-methylacrylate)(cas: 2358-84-1).Name: Oxybis(ethane-2,1-diyl) bis(2-methylacrylate)

Liu, Bin; Wang, Yanling; Liang, Lei; Zeng, Yijin published an article in 2021, the title of the article was Achieving solubility alteration with functionalized polydimethylsiloxane for improving the viscosity of supercritical CO2 fracturing fluids.Recommanded Product: Oxybis(ethane-2,1-diyl) bis(2-methylacrylate) And the article contains the following content:

Supercritical carbon dioxide (SC-CO2) fracturing technol. has the characteristics of a large amount of fixed CO2 and anhydrous fracturing. It has great application potential for developing unconventional oil and gas resources and mitigating the greenhouse effect. However, the low viscosity of SC-CO2 limits the development of this technol. In this work, HS series thickeners were prepared via a ring-opening polymerization and hydrosilylation reaction by a mol. simulation-aided design method. The simulation results of cohesive energy d., interaction energy, and radial distribution function are consistent with the visualization exptl. results, which proves that HS (hyperbranched siloxane) series thickeners have excellent solubility in SC-CO2. HS-3 is the best thickener in the HS series. At 305.15 K and 10 MPa, 5 wt% HS-3 (60 s-1) increases the viscosity of SC-CO2 by 151 times, and the apparent viscosity is 3.024 mPa s. The apparent viscosity of SC-CO2 was pos. correlated with the pressure and concentration but neg. correlated with the temperature and shear rate. The results indicate that it is feasible to introduce an aliphatic group and polysiloxane into a SC-CO2 thickener by hydrosilylation.

On January 5, 2022, Korzhikova-Vlakh, Evgenia G.; Tennikova, Tatiana B. published an article.Reference of Oxybis(ethane-2,1-diyl) bis(2-methylacrylate) The title of the article was Some factors affecting pore size in the synthesis of rigid polymer monoliths: Theory and its applicability. And the article contained the following:

Macroporous monoliths represent now widely used materials whose successful application strongly depends on their characteristics. Among those the average pore size is one of the key parameters. In this paper, we consider the applicability of theor. calculations for the selection of appropriate porogens to generate the materials with required average pore size. A set of macroporous poly(meth)acrylate monoliths was synthesized via thermo- and photo-initiated free radical polymerization and characterized in regards to their average pore size. Addnl., the difference in solubility parameters as well as Hansen’s solubility parameter distance between monomers and porogens were calculated for each polymerization mixture using Hildebrand’s and Hansen’s solubility theories. The theor. predications and exptl. data were compared and analyzed to establish the applicability of theor. calculations to previse average pore size for different systems. It was found that Hildebrand’s theory seems to be poorly appropriate as universal tool, while Hansen’s theor. approach explained better the efficiency of solvents as porogens. The application of oligomers and polymer solutions due to the increase of viscosity as well as the variation of crosslinker amount in the monomer system can be singled out as Hansen’s theory limitations at the prediction of the average pore size.
