A B S T R A C T The invention relates to the N-substituted acyl-lactam com- pound of the formula: Image where - R' is a bivalent cyclic or non-cyclic alkyl, aralkyl, alkaryl or aryl radical - R" a radical having the following general formula Image wherein - R'" is H, alkyl, cycloalkyl, aryl, alkaryl or aralkyl, - Riv is H, alkyl, cycloalkyl, aryl, alkaryl or aralkyl where - R'" and Riv may jointly form a substituted or non-substituted cycloalkyl residue - n is 0 or 1 - (-L) represents a non-opened lactam ring and - x a numer > 1. It has been found that this group of compounds is very suitable as activator in the preparation of nylon polymers, more spe- cifically in the so-called RIM (Reaction Injection Moulding) or RRIM (reinforced RIM) systems, in which it is highly essential for the polymerization to take effect within a very short time.
