Abstract
The invention concerns an N-substituted carbamoyl-lactam compound characterized by the formula: ##STR1## where in the formula: R is a polyol radical from a polyol having the formula R--(OH).sub.xi, where .sub.xi is an integer.gtoreq.2 R' is an alkyl, whether or not cyclic aralkyl, alkaryl or aryl group, .sub.yi 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.
