ABSTRACT:
A homogeneous mixture of a polyanhydride and a polyepoxide is prepared by the copolymerization of an olefinically unsaturated monomer capable of polymerization by free-radical means with an olefinically unsaturated monoanhydride and an olefinically saturated polyanhydride in the presence of a polyepoxide and an anhydride accelerator without substantial anhydride-epoxide cross-linking. As an example, reinforcing glass fibers are impregnated with a solution of styrene, maleic anhydride, styrene-maleic anhydride copolymer, a diglycidyl ether of bisphenol A and 1-methylimidazole and the resin is thickened in situ by copolymerization of the styrene, maleic anhydride and styrene-maleic anhydride copolymer to form a moldable, homogeneous mixture of styrene-maleic anhydride copolymer, diglycidyl ether of bisphenol A, 1-methylimidazole and reinforcing glass fibers.
