A moulding composition comprises a fibrous reinforcement, an ethylenically unsaturated, essentially amorphous, polymer, a cross-linking agent copolymerizable therewith and, as a thickener and low profile/shrinkage control agent, a crystalline saturated polyester which (a) has a number average molecular weight of from 700-10,000 inclusive, (b) has a melting point within a range of from 50-140 DEG C inclusive, and (c) is soluble in an equal weight of the crosslinking agent at 100 DEG C and yet insoluble therein at 30 DEG C. r |
