PURPOSE:To produce a composition having remarkably improved cure shrinkage and giving a molded article having excellent surface smoothness, by compounding an unsaturated polyester, a specific ethylene-acrylic acid ester copolymer and styrene. CONSTITUTION:(A) 20-55pts.(wt.) of an unsaturated polyester having a molecular weight of 2,000-5,000 (preferably 150-200 per double bond) is compounded with (B) 5-30pts. of an ethylene-acrylic acid ester copolymer having an ethylene content of 10-50wt%, preferably 15-30wt% and (C) 40-65pts. of styrene. |
