Abstract

Process for the preparation of molded bodies, characterized by reacting with each other, by heating, a) a polyepoxy compound, b) a dicarboxylic acid of the formula I **(See formula)** in which R1 means an aromatic or cycloaliphatic radical and R2 means an aliphatic or cycloaliphatic radical, and c) a polycarboxylic anhydride, in amounts such that, for 1 equivalent of the polyepoxy compound a), 0.05 to 0.8 equivalents of dicarboxylic acid b) and 0.20 to 0, 95 mol of polycarboxylic anhydride c).
