ABSTRACT:
The invention is a reaction injection molded polyurethane of improved properties comprising the cured reaction product of a high molecular weight polyhydric polyether, a low molecular weight active hydrogen containing compound of at least two functionality and a polyisocyanate. The reaction product is cured by subjecting it to an ambient temperature of from about 290.degree.-425.degree. F. for a time sufficient to achieve an improvement in properties. The invention is also a method for making such polyurethanes.
