摘要：

1. A liquid composition comprising an intimate mixture of (l) a bismaleimide of the structure wherein R is a bivalent hydrocarbon radical, and (2) a liquid organic diamine, H NR'NH having a molecular weight between 750 and 12,000, and wherein R is a bivalent polymeric hydrocarbon radical selected from the group consisting of (a) radicals formed by the polymerization of ethylenically unsaturated monomers, at least 50% of which are conjugated dienes, and (b) the corresponding hydrogenated radicals; said ethylenically unsaturated monomers being selected from the group consisting of hydrocarbon monomers and halogen-substituted hydrocarbon monomers.
