A compounded unsaturated polyester resin composition having 10-90 wt % of at least one high viscosity, high molecular weight unsaturated polyester, 10-80 wt % of at least one low viscosity, low molecular weight unsaturated polyester, and 9-30 wt % of at least one monomer. The cone and plate viscosity of the high molecular weight unsaturated polyester is 1 Pas/100° C. to 10 Pas/150° C. and the weight average molecular weight Mw is 1,200 to 10,000. The cone and plate viscosity of the low molecular weight unsaturated polyester is 1 Pas/25° C. to 4 Pas/100° C., and the weight average molecular weight Mw is 400 to 3,000. |
