Abstract

PURPOSE: To prepare an easily handleable title compound which loses its tackiness in a short time, by reacting an unsaturated polyester resin containing a solid component having specific hydroxy value and acid value, with a polyisocyanate compound.
CONSTITUTION: Sheet molding compound is prepared by reacting (A) an unsaturated polyester resin containing a polymerizable monomer (e.g. styrene and methyl methacrylate) and a solid component having a hydroxy value of ≥20 and the ratio of hydroxy valye to acid value of ≥1.5, with (B) a polyisocyanate compound (e.g. tetramethylene diisocyanate). The isocyanate group of the (B) component is pref. completely reacted with the hydroxy group of (A) component, i.e. the molar ratio of the hydroxy group to the isocyanate group is pref. 0.7W1.3.
