Abstract

Abstract Copoly (arylene ether sulfone) s from 4, 4′-difluorodiphenyl sulfone, 4, 4′- dihydroxydiphenyl sulfone bis-trimethylsilylether, and 2, 5-diphenylhydroquinone bis- trimethylsilylether were obtained by nucleophilic displacement polycondensation with high molecular weights. While the random copolymers were obtained with narrow molecular weight distributions, the molecular weight distributions of the multiblock copolymers were ...
