Acid halide and acyllactam functional materials, which are useful in the preparation of nylon block polymers, selected from the group consisting of those of the formulae:
wherein,
A is X or Q;
X is halogen;
Q is
with Y = C3-C11 alkylene;
b is an integer equal to 2 or more;
R, is an alkyl, aryl, aralkyl, alkoxy, halogen, Q, aryloxy, or aralkyloxy groups;
Z is a segment of: (1) a polyether having a minimum molecular weight of 2,000; or (2) a polyester containing polyether segment having minimum molecular weights of about 2,000. Also described is a process for preparing a nylon block polymer which comprises bringing into reactive contact lactam monomer, basic lactam polymerization catalyst and an acyllactam functional material of the above formulae wherein A is Q.
