ABSTRACT:
Reaction injection molded polyurethanes prepared from a composition comprising (A) a relatively high molecular weight polyol, (B) a chain extender and (C) an aliphatic polyisocyanate or polyisothiocyanate are improved by replacing a portion of the relatively high molecular weight polyol with an aminated or partially aminated polyoxyalkylene material.
