Abstract
Polyimide polymers which are reaction products of active methylene compounds and N,N'-bismaleimide derivatives are improved by incorporating them with 2 to 15% by weight of a polyethersulfone polymer. The polymer blend is useful in producing films, moldings, prepegs, laminates and filled composites which are particularly useful in structural components which have stability at high temperatures.
