A new class of copolymers obtained via the copolymerization of diethynylbenzene with an ethynyl-substituted polyimide oligomer has been used to prepare composite materials exhibiting zero void content. 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.

Ethnyl terminated polyimide composites

A new system of epoxy resins and curing agents is disclosed which may be cured at low temperatures to yield polymeric materials capable of providing excellent binders for filled systems. The new combination exhibits a useful pot life, and cures at low temperatures to form a tough, dimensionally stable polymer.
