Abstract
High-molecular-weight block copolymers of polycaproamide and polyethylene glycol were synthesized and are distinguished by the different size of the polyamide block and number of polyamide and polyethylene oxide blocks in the macromolecule. In the conditions of synthesis of the copolymers used. their molecular characteristics are in good agreement with the calculated characteristics, and the melting point is a linear function of the reciprocal of the average degree of polymerization of the polyamide block in the copolymer. An opinion was advanced concerning the expedient regions of practical use of block copolymers differing in the ratio of stiff (polyamide) and flexible (polyethylene oxide) blocks.
