ABSTRACT:
Fully cured calcium carbonate filled polyisocyanurate/polyurethane sheet molding compositions are improved in blister resistance at temperatures of 175.degree.-205.degree. C. by the incorporation therewith of from 0.05-2% based upon the weight of the carbonate of a polybutadiene telomers maleic anhydride addition products. Such compositions are most blister resistant when the polybutadiene telomer/maleic anhydride addition product is mixed with the resin ingredients prior to the addition of carbonate filler.
