Abstract

Curable polyester molding materials contain a mixture of PA1 A. an ethylenically unsaturated polyester or a vinyl ester possessing an unsaturated terminal group, PA1 B. copolymerizable monomers, PA1 C. fibrous reinforcing agents, PA1 D. powdered fillers, PA1 E. organic free radical initiators, PA1 F. a viscosity depressant and PA1 G. conventional additives. The viscosity depressant is a tertiary or secondary amine which carries a long-chain alkyl or acyl group and a carboxyl group.
