Abstract

Polyimide prepolymers formed by thermo-reactions of an aliphatic bismaleimide, where the aliphatic group is a polyaliphatic ether, with an aromatic bismaleimide and/or an aromatic diamine in combination with a cross-linking agent having at least two vinyl groups provide compositions which are curable at low temperatures, i.e., 65.degree. C. or less.
