Abstract

Liquid, curable, unsaturated polyester resin compositions having improved inherent adhesion to the surface of their pre-cured composition after processing has been interrupted for an extended period. In order to enable damage-free extension of processing interruptions while simultaneously reducing the emission of styrene, the reactive compositions based on unsaturated, copolymerisable polyester resins, styrene, catalyst and reaction accelerator are treated with an additive combination comprising up to 2% by weight of an additive component A and up to 8% by weight of an additive component B, in each case based on the unsaturated copolymerisable polyester resin. A) here is a wax-like organic substance having a melting point of <90 DEG C, preferably <120 DEG C, and B) is a modified, liquid epoxy resin or a styrene-soluble polymer containing monomer units derived from vinyl esters or vinyl acetals and having a melting point of between 40 and 170 DEG C. The liquid, reactive compositions are used to produce thermoset mouldings or moulded parts or materials reinforced with glass fibres or mono- or polylaminated with glass fibres.
