Abstract
A polyisocyanate composition, suitable for use in the production of elastomers by the RIM process, or foams, said composition being the product of reacting an imino-functional or enamine-containing compound having a molecular weight of at least 1000 with a stoichiometric excess of an organic polyisocyanate.
