organic chemistry, polymers. SUBSTANCE: invention describes block-polymer with molecular mass at least 10 000 Da and presenting the reaction product of isocyanate with polyester and aliphatic or aromatic diamine in the mole ratio NH2/NCO in the range 0.95-1.05 comprising urea, urethane and ester groups and, except for, primary NH2- and/or OH-terminal groups that can be substituted by monoamino-group, butylamine or ethylamine and forming fragments after hydrolysis of esters easily excreting from human body. Also, the invention describes a method of synthesis the above-mentioned linear block-polymer. The proposed linear block-polymer is used in implants for living organisms, for example, as an implant as bundles. EFFECT: improved method of synthesis, valuable properties. 12 cl, 9 ex |
