摘要
Block copolymers may contain polybenzazole blocks and blocks of polybenzoxazinone polymer or polyoxadiazole polymer. The block copolymers may be coagulated from isotropic dopes to form shaped articles or granular compositions. The granular compositions may be compression molded to form molded articles. The block copolymers may be molded at high temperatures without substantial phase separation, and the polybenzazole polymer provides support to improve the tensile propoerties of the polymer.
