Abstract
A polyester resin composition is disclosed. The composition consists essentially of a blend of a diethylene glycol:neopentyl glycol:maleic:isophthalic acid polyester and a propylene glycol:isophthalic acid:maleic polyester, together with a copolymerizable monomer in an amount sufficient for reaction with the polyester blend to produce a thermoset article. In a preferred disclosed composition, the blend is composed from about 5 to 15 percent by weight of the diethylene glycol polyester and from about 95 to 85 percent of the propylene glycol polyester, together with from 35 to 45 percent by weight of styrene as a copolymerizable monomer, based upon the weight of the polyester blend and styrene.
