Patent

CA 1252090

A B S T R A C T The invention relates to N-substituted acyl lactam compounds of the formula Image where - R is a polyol residue originating from a polyol with the formula R-(OH)X where x is a number > 2 - R' a bivalent cyclic or non-cyclic alkyl, aralkyl, alkaryl or aryl radical - R' a bivalent 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 O or l and - (-L) represents a non-opened lactam ring of the formula Image wherein Y is a hydrocarbon residue with 3-11 carbon atoms. It has been found that this group of compounds is very suitable as activator in the preparation of nylon block copolymers, more specifically in the RIM or RRIM systems.
