Method of preparation of terpolymers lactam - polyol - polyacyl or acylpolylactame and novel products thus obtained

摘要

A process for preparing lactam-polyol-polyacyl lactam or acyl polylactam terpolymers having ester end group termination and both ester linkages and amide linkages between the monomeric segments. The terpolymers are prepared by initiating the anionic catalyzed polymerization with a polyester initiator formed from dicarboxylic acid esters and aliphatic polyols and/or aliphatic polyether polyols.
