METHOD OF (CO)POLYMERS PRODUCING

摘要

FIELD: polymers, chemical technology. SUBSTANCE: "living" polymer is obtained by (co)polymerization of coupled diolefins in the presence of organolithium compound. Chain is broken off by addition of hydrogen or its isotope and its contacting with its polymerizing agent is carried out for at least 10 s at 0-100 C under pressure 0.07-138 bars. Invention can be used for producing block-copolymers based on coupled diolefins. EFFECT: improved method of synthesis. 6 cl, 1 tbl,
