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
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
