ABSTRACT:
A thermosetting unsaturated polyester resin composition comprising (a) an unsaturated polyester, (b) a modified block copolymer comprising a block copolymer of vinyl aromatic compound and conjugated diene compound onto which an unsaturated dicarboxylic acid and/or an unsaturated dicarboxylic acid derivative is grafted, (c) a vinyl monomer, (d) a curing agent and, if necessary, (e) other additives, the amounts of said (a), (b) and (c) constituents being 10 to 90 parts by weight, 2 to 70 parts by weight, and 10 to 80 parts by weight, respectively, the total amount of (a), (b) and (c) being 100 parts by weight, and the proportion of (d) being 0.1 to 10 parts by weight per 100 parts by weight of the total amount of (a), (b) and (c). The above composition is excellent in impact resistance, surface characteristics and rigidity.
