METHOD OF PREPARATION OF CIS-1,4-POLYBUTADIENE AND CIS-1,4- BUTADIENE-ISOPRENE COPOLYMER Russian patent published in 1997 - IPC

Abstract RU 2087488 C1

FIELD: chemistry of high-molecular weight compounds, more particularly petrochemical industry. SUBSTANCE: present invention describes method of preparation of CIS-1,4-polybutadiene and butadiene-isoprene copolymer in hydrocarbon solvent in the presence of catalyst obtained by reaction of carboxylate compounds of rare-earth metal compound with halogen-containing organoaluminium compound in the presence of conjugated diene. The organoaluminium compound includes mixtures of dialkyl aluminium hydride, trialkyl aluminium and tetraalkyl dialumoxane. The claimed method makes it possible to increase substantially catalyst activity. EFFECT: more efficient preparation method. 2 cl, 1 tbl
