Abstract
FIELD: technology of high-molecular compounds, polymers. SUBSTANCE: method involves polymerization of butadiene in aromatic solvent under effect of catalyst made on the basis of rare-earth element compounds; after polymerization process termination polymerizate is mixed with polyhexene-1 solution in aromatic solvent at polymer ratio 5-20 mas. p. polyhexene-1 per 100 mas. p. cis-1,4-polybutadiene. Method can be used in petrochemical industry. EFFECT: synthesized cis-1,4-polybutadiene shows decreased plasticity and cold flowing, high physico-mechanical properties.
