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

Abstract RU 2099357 C1

FIELD: production of high molecular weight compounds, particularly, production of stereoregular polydienes with the help of Zielger-Natte type catalytic systems; petrochemistry. SUBSTANCE: method is carried out by polymerization of butadiene, the process takes place in aromatic solvent with the help of catalyst. Said catalyst comprises neodium salt of alpha-substituted monocarboxylic acids, chloro-containing compound, diene and trialkyl aluminium; complex of aluminium trichloride with diphenyl oxide being used as chloro-containing compound. EFFECT: decreased plasticity of desired 1,4-cis-polybutadiene having high physical and mechanical properties. 2 tbl
