The invention relates to the N-substituted acyl-lactam compound of the formula: [Figure] where R′is a bivalent cyclic or non-cyclic alkyl, aralkyl, alkaryl or aryl radical R″a bivalent radical having the following general formula [Figure] wherein R′″is H, alkyl, cycloalkyl, aryl, alkaryl or aralkyl,
The invention relates to the N-substituted acyl-lactam compound of the formula: [Figure] where R′is a bivalent cyclic or non-cyclic alkyl, aralkyl, alkaryl or aryl radical R″a bivalent radical having the following general formula [Figure] 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 number>1. It has been found that this group of compounds is very suitable as activator in the preparation of nylon polymers, more specifically 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.
