FIELD: chemistry. ^ SUBSTANCE: present invention relates to resorbable block copolymers for producing resorbable surgical or therapeutic implants for humans and animals. The block copolymer is of type AB or ABA. Block A is formed by polyester and block B is formed by polyether. Type AB has the formula: E-(O-D-CO-)n-(O-CH2-CH2-)m-O-F, where the structural link E-(O-D-CO-)n forms block A, and link -(O-CH2-CH2-)m forms block B. Type ABA has the formula: E-(O-D-CO-)n-(O-CH2-CHr)m-O-(CO-D-O-)n'-E, in which links E-(O-D-CO-)n and E-(O-D-CO-)n. form block A, and link -(O-CH2-CH2-)m forms block B. Content of block B ranges from 0.1 to 4 wt %. The invention also relates to a method of producing and cleaning said block copolymers contaminated with monomers. ^ EFFECT: obtaining block copolymers or implants from said block copolymers, characterised by high mechanical strength, elasticity, viscosity and fast kinetic resorption. ^ 42 cl, 3 tbl, 4 ex |
