ABSTRACT:
Sheet moulding compounds based on thermosetting unsaturated polyester resins contain a saturated liquid polyester having a melting point below 30.degree.C, for example polypropylene adipate or polypropylene sebacate to prevent shrinkage during moulding, and a thermoplastic polymer consisting essentially of polymerized caprolactone units to prevent exudation of the saturated liquid polyester during moulding.
