Thiophene-Based Poly(Arylene Ether)s: 5. Imide-Arylene Ether StatisticalCopolymers

摘要

Imide-aryl ether thiophene copolymers were prepared and their thermal andmechanical properties were investigated. A key feature of these copolymers is the incorporation of the 2,5-thiophene moiety using 5,5'-bis((3-aminophenoxy) thienyl-2) ketone or 5,5'-bis((4-aminophenoxy)thienyl-2) ketone diamines in polyimide syntheses. The preparation of these thiophene diamines involved the nucleophilic
