ABSTRACT:
The invention relates to sheet molding compounds having improved viscosity control comprising polyester-polyurethane hybrid resins formed by the reaction of an A side composition and a B side composition. The A side composition comprises a polyfunctional isocyanate compound and a free radical polymerization catalyst. The B side composition comprises a mixture of (i) an ethylenically unsaturated monomer solution having no active hydrogen groups which has dissolved therein about 40-90 weight percent of a substantially water-free, unsaturated polyester polyol having at least one dicarboxylic alkene moiety and having an acid number less than five; and (ii) a methacrylate ester of a C.sub.2 -C.sub.10 alkylene diol.
