Abstract: The invention concerns an N-substituted carbamoyl-lactam compound characterized by the formula:where in the formula:- R is a polyol radical from a polyol having the formula R-(OH) xi , where xi is an integer ≥ 2- R' is an alkyl, whether or not cyclic aralkyl, alkaryl or aryl group, xi is an integer > 0,- (-L) is an unopened lactam ring and- (-L-) is an opened lactam block. The compounds are highly suited for use as activators in preparing nylon block copolymers.
