## Abstract A method to determine the concentration of ϵ‐aminocaproic acid (ACA) in poly‐ϵ‐caprolactam by high‐pressure liquid chromatography is established. The polymerizations for initial water concentrations of 0.42, 0.82, and 1.18 mol/kg and temperatures of 230, 240, 250, 260, 270, and 280°C we
A~tract--Block copolymers polycaprolactam-polyoxyethylene-polycaprolactam were prepared by anionic polymerization of caprolactam activated with ~,~o-dicarbonylcaprolactam-polyoxyethylenes and characterized by the content of the polyether component, crystallinity of the polyamide component and sorpti
The non-activated polymerization of e-caprolactam initiated with the sodium salt of e-caprolactam (CLNa), which was prepared in situ with sodium methoxide, was studied in the temperature range 170 -230 8C and at CLNa concentrations from 0.20 to 1.0 mol-%, and at 190 8C in the presence of 2.0 -10.0 m
