ABSTRACT:
A novel bis-imide matrix resin composition comprising (i) 40 to 95 percent by weight of ethyleneically unsaturated bis-imides, preferably a low melting mixture of a major portion of maleimides of aromatic amines such as toluene diamine and methylene dianiline with a minor portion of maleimide of an aliphatic amine such as trimethyl hexamethylene diamine, (ii) 5 percent to 60 percent by weight of a heatactivatible cross-linking agent combination for gelling the bis-imides, said combination comprising (1) an arylene polyamine and (2) an alkenylphenol or alkenylphenol ether, and, as a polymerization catalyst therefor, (iii) an imidazole compound. The resin composition is useful as a matrix resin for high performance, fiber reinforced composites, having low shrinkage, good thermal stability and moisture resistance and excellent impact strength.
