Abstract
Styrene-free unsaturated polyester resin compositions are provided which have low volatile organic compounds and hazardous air pollutants emissions when these resin compositions are used in open molding applications. A process for the manufacture of these resin compositions is provided.
Claims22
A styrene-free unsaturated polyester resin composition consisting essentially of (1) a dicyclopentadiene-based unsaturated polyester;
- (2) a urethane (meth)acrylate;
- (3) a multifunctional (meth)acrylate monomer and (4) from 5-60 percent by weight of a hydroxyl-functionalized (meth)acrylate monomer, wherein the resin composition after cure has a heat distortion temperature (ASTM D-648) of at least 65° C.
