ABSTRACT:
An unsaturated polyester resin composition is provided comprising a hard unsaturated polyester component, a soft unsaturated polyester component and a cross-linking monomer. The soft polyester component contains a polyoxyalkylene segment having a molecular weight from 600 to 6000 in the backbone thereof and is dispersed in the hard polyester component forming fine particles having a particle size not greater than 4 microns. The resin composition, when cured, exhibits a Tg corresponding to the hard polyester component from 100.degree. C. to 200.degree. C. and another Tg corresponding to the soft polyester component from -100.degree. C. to 0.degree. C.
