Abstract
A quickly curable unsaturated polyester composition with high surface quality contains an unsaturated polyester, a vinyl monomer, either an alkane polyol polyacrylate or an alkane polyol polymethylacrylate, a thermoplastic resin, and one or more curing catalysts selected from t-butylperoxy benzoate, t-butylperoxy octoate and 2,5-dimethyl-2,5-di(benzoilperoxy) hexane. Molding compounds are obtained by impregnating glass fibers with such composition and molded products obtained by curing such molding material have improved surface smoothness.
