Novel Linear and Cross-Linked Acrylate Polymers Bearing O-Cyanoethylated (Glycosyloxy)ethyl Side Chain with High Dielectric Properties over Wide Temperature Range

摘要

UV-irradiation (365nm) on a spreaded mixture of 2-[tetra-O-(cyanoethyl)glucopyranosyloxy]acrylate and ethylene glycol dimethacrylate onto a copper plate gave a cross-linked copolymer which exhibited extremely stable and high dielectric permitivity (#epsilon#')of 23 to 30(-100 to -10 deg C) and as high as 49 even at 20 deg C.
