Abstract
Abstract Three novel bisphenols containing pendant ethynyl, hexynyl, and phenylethynyl groups were synthesized and used to prepare arylene ether polymers and copolymers. When heated to 250–350°C, the ethynyl groups react. After curing, the homopolymers were brittle due to the high crosslink density. Copolymers prepared using either 10 or 30 mol% of the ethynyl-containing bisphenol and either 90 or 70 mol% of the bisphenol with no ethynyl groups were relatively tough and formed creasible films. After a thermal cure, the copolymers became insoluble and exhibited high T gs and good thin film tensile properties.
