Abstract
AbstractThe kinetics of alcoholysis of bis(N‐acyl‐6‐hexanelactams) and bis(N‐carbamoyl‐6‐hexanelactams) was studied for the purpose of the preparation of bifunctional polymeric initiators of the anionic polymerization of 6‐hexanelactam used in the production of polyamide block copolymers by reactive processing. The reaction was carried out with 1‐octanol as a model alcohol and with poly(propylene oxide)diol, without catalysis or using anionic and polyesterification catalysts, and in 6‐hexanelactam as a solvent. Applicability of this functionalization method is discussed with respect to a broad spectrum of formed products, competition of lactam oligomerization in the presence of basic catalysts, preparation of the initiator component for two‐component polymerization systems, and in situ functionalization during polymerization. © 1992 John Wiley & Sons, Inc.
