Abstract
The results of the studies concerning photo- and thermally initiated copolymerization of bis[4(2-hydroxy-3-methacryloyloxypropoxy)phenyl]sulfide (BES-DM) with N-vinyl-2-pyrrolidone (NVP) and thermo-mechanical properties of resulting compositions are presented. BES-DM was obtained in the two-step reaction. In the first step, the epoxy resin was synthesized. It was obtained in the reaction of bis(4-hydroxyphenyl)sulfide with 2-(chloromethyl)oxirane. In the second step, esterification of the obtained diglycidyl ether was carried out with the use of methacrylic acid. New copolymers with different degrees of crosslinking were obtained. The study describes the effect of crosslinking degree and the method of polymerization initiation on the properties of the new compositions. Density, viscosity, glass temperature, Young’s modulus, hardness, tensile strength were determined before and after curing for the compositions of BES-DM and NVP. Moreover, the dynamic-mechanical and thermal properties for the chosen samples of copolymers were studied.
