Abstract

Reactive resin systems suitable for cast-molding polyurethanes comprise reactive isocyanates and chain extenders for the isocyanates comprising polyol addition products of C.sub.1 -C.sub.8 alcohols and epoxidized triglyceride oils: if desired, the polyol addition products used have been alkoxylated with C.sub.2 -C.sub.4 -alkylene oxides.
