ABSTRACT:
An isocyanate-reactive polymer comprising the reaction product of: (a) an isocyanate-terminated polyurethane prepolymer formed by reacting a polymeric polyol having a hydroxyl equivalent weight of at least 500 with a stoichiometric excess of an organic polyisocyanate, and (b) a stoichiometric excess, relative to the free isocyanate groups present in the prepolymer, of an imino-functional or enamine containing compound having a molecular weight less than about 750. The polymer is useful in reaction injection molding systems as an isocyanate-reactive ingredient.
