ABSTRACT:
Hydroxy-terminated telechelic rubber polymers and block copolymers of flexible polymers with unsaturated polyester resins improve the elongation and flexural elongation of in-mold coating compositions for fiber reinforced plastics (FRP). An FRP in-mold coating composition based upon vinyl ester resin, ethylenically unsaturated monomers, and at least one of telechelic hydroxy terminated flexible polymers and the block copolymers of functionally terminated flexible polymers with unsaturated polyester polymers are described.
