Abstract
This development provides glycidyl-acrylates that, when copolymerized with unsaturated polyesters, provide high performance, structural SMC products. The acrylates increase the reactivity of the polyesters. One result has been "zero shrinkage" parts with good heat distortion, pigmentability and excellent mechanical and physical properties.
