Abstract

A thickened, uncrosslinked molding composition which has a long shelf life and can be cured above 50.degree. C. comprises a liquid reactive system, a thickener, a polymerization initiator and conventional additives. The thickener is a combination of a primary aromatic amine and an isocyanate. The molding compositions, which are, in particular, SMCs or BMCs, can be processed into moldings by compression molding, injection molding or transfer molding and subsequent curing.
