Structure of Hydrogels and Activity of Proteins Immobilized in Them Polym. Sci. Ser. B (IF 1.049) Pub Date : 2021-09-01 Valuev, I. L., Vanchugova, L. V., Gorshkova, M. Yu., Sivov, N. A., Valuev, L. I.
Abstract The effect of the chemical structure of crosslinking agents on the activity of proteins in hydrogels obtained by the copolymerization of acrylamide, a crosslinking agent, and an unsaturated protein derivative is studied. It is shown that interaction between units of the hydrophobic crosslinking agent which increases with an increase in the length of the aliphatic region between the double

Investigating the Electrical Properties of Epoxy Resin Containing MWCNT–PANI with a Core-Shell Morphology: Synthesis and Characterization Polym. Sci. Ser. B (IF 1.049) Pub Date : 2021-09-01 Sahar Rashidifard, Amraei, Iraj Amiri, Heidar, Hamid, Mousavi, Seyed Rasoul
Abstract The aim of this study was to synthesize doped polyaniline and carboxylate multi-walled carbon nanotubes-polyaniline nanocomposites with a core-shell morphology, in HCl (PANI/HCl and MWCNT−PANI/HCl, respectively) and camphorsulfonic acid (PANI/CSA and MWCNT−PANI/CSA, respectively) media and to investigate the effects of these media on electrical properties. The synthesized samples were characterized

Structure of the Products of Hydrolytic Copolycondensation of 3-Aminopropyltriethoxysilane and 3-Methacryloxypropyltrimetoxysilane: NMR Study Polym. Sci. Ser. B (IF 1.049) Pub Date : 2021-09-01 Bredov, N. S., Nguyen, Van Thuan, Zaitseva, D. S., Kireev, V. V., Gorlov, M. V., Sokol’skaya, I. B., Polyakov, V. A.
Abstract According to 1H, 13C, and 29Si NMR spectroscopy, in the hydrolytic copolycondensation of 3‑aminopropyltriethoxysilane and 3-methacryloxypropyltrimethoxysilane, side reactions of addition of amine groups to methacrylate groups (the Michael reaction), as well as partial hydrolysis and transesterification of ester bonds, occur along with the main process of the formation of oligomeric silsesquioxanes

Features of Thermo-Oxidative Degradation of Epoxy Oligomer-Based Compositions with Thermoplastic Fillers Polym. Sci. Ser. B (IF 1.049) Pub Date : 2021-09-01 Shibryaeva, L. S., Gorbunova, I. Yu., Kerber, M. L., Povernov, P. A.
Abstract The effect of fillers, polysulfone and polyetherimide, on the mechanism and kinetics of the thermo-oxidative degradation of a composition based on an epoxy oligomer cured with 4,4'-diaminodiphenyl sulfone which proceeds under heating in the nonisothermal regime is studied. A relationship is revealed between the structure of the composition and the mechanism and kinetic parameters of the process

Synthesis of Novel Fluorinated Poly(aryl ether ketone)s and Their Properties Polym. Sci. Ser. B (IF 1.049) Pub Date : 2021-09-01 Qingze Jiao, Li, Na, Zhang, Pei, Wang, Shanshan, Zhao, Yun, Feng, Caihong, Lv, Yuzhen
Abstract A novel bisphenol monomer, (4-trifluoromethyl) phenylhydroquinone, was synthesized using a three-step synthetic procedure. Two aromatic poly(aryl ether ketone)s were then prepared via a nucleophilic polycondensation reaction of (4-trifluoromethyl) phenylhydroquinone and two difluorinated aromatic ketones, respectively. As-synthesized poly(aryl ether ketone)s show a high thermal stability,
