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.

Isocyanate reactive polymers having imino/enamine functionality

Polyisocyanate compositions with useful properties are obtained by reacting uretonimine and/or carbodiimide modified polyisocyanates with carboxylic acids. The polyisocyanate compositions are useful in the preparation of elastomeric products.

Polyisocyanate compositions

A reaction system is provided for use in forming polyureas by the reaction injection molding process which employs an enamino-functional polyether resin as an isocyanate-reactive component.
