ABSTRACT:
Polyimide copolymers which are reaction products of active methylene compounds and N,N'-bismaleimide derivatives are improved by incorporating them with 2-20% by weight of a polyetherimide polymer having arylimide bonds, arylene bonds and ether bonds. The polymer blend is useful in films, moldings, prepregs, laminates and filled composites which are particularly useful in structural components which have stability at high temperatures.
