Abstract

The solution concerns a method of preparation of block copolymers of ε-caprolactam by anionic polymerization initiated by alkaline salts of ε-caprolactam or their precursors, in presence of 0.1 to 40 percent by weight, optimally from 1 to 15 percent by weight of low-molecular-weight polymers with hydroxyl, carboxyl and amino terminal functional groups, and is activated by monofunctional isocyanates or their cyclic compounds, while the polymerization proceeds for a period of 1 to 200 minutes at a temperature of 130 to 260 degrees C.
