ABSTRACT:
A thermosettable composition suitable for preparing reinforced plastic articles is prepared by combining an unsaturated polyester, a normally solid carboxy-containing polymer of a conjugated diene, a vinyl monomer, a catalyst and a reinforcing agent or filler. Preferably the composition is prepared utilizing a mixer giving moderate shear such as a twin-rotor mixer. The resulting composition when cured exhibits high impact strength and good surface finish.
