Beschreibung
Zusammenfassung:	The invention concerns a process for preparing an N-substituted carbamoyl-lactam compound having the formula by reactively admixing a polyhydroxy compound having the formula R(OH)n and a polyisocyanate having the formula OCN-R min -NCO, wherein said n is an integer >/=3, R is the residual of a three or higher functional polyhydroxy compound, R min is an alkyl, aryl, alkaryl, or an aralkyl group having 6-25 carbon atoms, and Y is a C3-C14 alkylene group and reacting the product thereof with at least one lactam. The product prepared accordingly can advantageously be used in the preparation of nylonblockcopolymers, and more in particular in the reaction injection moulding of nylon.
