METHOD FOR SYNTHESIS OF CIS-1,4-POLYBUTADIENE Russian patent published in 1997 - IPC

Abstract RU 2088599 C1

FIELD: chemical technology, organic chemistry. SUBSTANCE: method involves polymerization of butadiene in hydrocarbon solvent in the presence of catalyst - product of interaction of organoaluminium compound and titanium halide hydrocarbon solutions, deactivation of catalyst, stabilization of polymer, isolation of polymer from solution and drying by the known methods. Method involves also the use of isobutylene taken at ratio 0.1-200% to monomer. EFFECT: improved method of synthesis. 1 tbl
