Abstract

A hardenable polyester molding material contains a mixture of PA0 I. an ethylenically unsaturated ester or a terminally unsaturated vinyl ester, PA0 II. copolymerizable monomers, PA0 III. 6-25% by weight, based on I+II, or a graft polymer P, in which there are grafted on PA1 A. 5-95% by weight of an elastomeric polymer, PA1 B. 95-5% by weight of a polyadduct, polycondensate or acrylic polymer which contains olefinic double bonds, with or without PA1 C. 0-90% by weight of vinyl monomers, and PA0 IV. 5-300% by weight, based on I+II, of fibrous reinforcing agents.
