Process for the manufacture of prepolymerizations and moldings based thereon, characterized in that to mixtures of unsaturated polyesters and monomeric compounds polymerizable therein with a content of gelling agents and, optionally fillers, catalytic amounts are added. a 1,2-substituted ethane derivative of the general formula ** (See formula) ** wherein R1 and R3 are aromatic moieties, R2 is hydrogen or an aliphatic or aromatic moiety, R4 is an aliphatic or aromatic moiety and X and Y are an optionally blocked hydroxyl group and/or an optionally substituted and/or halogen NH2 group, in amounts such as from about 0.1 to 10%, based on the mouldable masses, and the mixtures are heated to temperatures at which the aforementioned ethane derivatives do not yet cause the polymerization, until the masses have passed into the gelled state, and then cooled , it having been foreseen that for the subsequent obtaining of molded bodies, based on them the prepolymerized ones themselves are heated up to temperatures at which the aforementioned ethane derivatives originate the polymerization.
