ABSTRACT:
A process is disclosed for producing molded parts from a polyester-based curable molding composition which includes a thermostetting unsaturated polyester resin, an ethylenically unsaturated monomer which is copolymerizable with the unsaturated polyester resin to provide crosslinking, a thermoplastic low profile additive material for shrinkage control and in addition, at least one highly reactive olefinically unsaturated crosslinkable monomer, this highly reactive olefinically unsaturated material being selected from the group consisting of:
