Abstract: The compounds of the present invention are obtained by the reaction of carbamoyl lactams (from lactams and polyisocyanates) with polyhydric alcohols or monoamino alcohols in the presence of catalytic quantities of a strong basic catalyst, e.g. an alkali metal alcoholate, at elevated temperatures. The polyols contain urea groups and either ester or amide groups and correspond to formula (I) or (II) (I) (II) The polyols are crystalline, relatively high melting compounds which are used as reactants for the synthesis of polyurethane elastomers, in particular in the form of finely divided components in one-component polyurethane reaction mixtures.

Abstract: The present invention is directed to a process for the production of a polyurethane urea elastomer which comprises preparing a heterogeneous mixture of (a) a diaminodiphenylurea corresponding to the formula wherein R1, R2, R3 and R4, which may be the same or different, represent hydrogen or a C1-C6 alkyl radical and wherein the amino groups are in the meta and/or para position to the urea group and (b) polyisocyanates and NH2-or OH-groups containing compounds or a NCO-terminated prepolymer prepared from a polyisocyanate and a polyhydroxyl compound having a molecular weight of 400 to about 10,000, and subsequently reacting the heterogeneous system to form a polyurethane urea elastomer by heating the mixture to a temperature below the melting point of said diaminodiphenylurea. The present invention is also directed to heterogeneous reaction mixtures based on the above diaminodiphenylureas suspended in the above NCO-terminated prepolymers.
