Abstract

Epoxidized and subsequently cross-linked esters of alcohols which are at least dihydric and unsaturated fatty acids may be used as active processing substance in polymers, in particular elastomers, at higher temperatures, in particular at higher vulcanization temperatures, than "Factice". They may be produced by a particularly elegant one-shot reaction.
