METHOD OF SYNTHESIS OF BLOCK-COPOLYMERS CARRYING OUT BY CONTROLLED RADICAL POLYMERIZATION Russian patent published in 2003 - IPC

Abstract RU 2204568 C2

FIELD: chemistry of polymers, chemical technology. SUBSTANCE: invention relates to novel method of radical polymerization allowing to prepare block-copolymers and to block-copolymers prepared by this method. Method involves interaction of ethylene-unsaturated monomer of the formula CYY′(=CW-CW′)_a=CH₂, compound-precursor synthesized by radical polymerization of ethylene-unsaturated monomer of the formula CXX′(=CV-CV′)_b=CH₂ in the presence of alkylxanth, initiating agent of radical polymerization. Invention provides the development of method of controlled radical co-polymerization for preparing block-copolymers with low index of polydispersion and having chain terminal functional groups. EFFECT: improved method of synthesis. 16 cl, 12 tbl
