Abstract
Thermoset resinous molding compositions are provided by essentially instantaneously combining and reacting three basic resin forming components. The latter include an oligomeric ester or polyester containing polymerizable unsaturation and free hydroxyl group(s); a polyisocyanate; and an aromatic polyamine. The indicated thermosetting resin systems are especially adapted for use in a reaction injection molding (RIM) operation.
