摘要
A new class of copolymers obtained via copolymerizing diethynylbenzene with an ethynyl substituted polyimide oligomer has been developed. The copolymers are thermosetting in character and are particularly useful for the fabrication of composite structures such as glass fiber reinforced laminates and molding compounds and graphite fiber reinforced laminates and molding compounds having zero void content.
