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
In the reaction between the potassium salt of E-caprolactam and N-propionyl-e-caprolactam or N-benzoyl-~-caprolactam in tetrahydrofuran at 25;, the consumption of both reactants and the formation of structures giving ketones by hydrolysis were investigated. Analysis of the data allowed determination
