Abstract
A prepolymer comprised of the reaction product of at least one aliphatic bismaleimide, at least one aromatic amine and at least one aromatic bismaleimide is combined with at least one cycloaliphatic epoxy resin having a melting point less than about 120.degree. F. and at least two functional epoxy groups to provide a low temperature curable composition. The cured products are strongly adherent to a variety of substrates.
