POLYHYDROXY COMPOUNDS CONTAINING UREA GROUPS AND EITHER ESTER OR AMIDE GROUPS, PROCESS FOR THEIR PREPARATION, AND THEIR USE THEREOF ABSTRACT OF THE DISCLOSURE 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) Image (I) Image (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.
