PROCESS FOR PREPARING CIS-1,4-POLYISOPRENE Russian patent published in 1995 - IPC

Abstract RU 2041886 C1

FIELD: petrochemical industry. SUBSTANCE: in a process for preparing cis-1,4-polyisoprene, in order to prevent inferior plastic and elastic properties of the final products when a catalyst complex is deactivated with water, the molar ratio the catalyst complex is adjusted, the molar ratio of the components of triisobutyl aluminium catalyst and titanium tetrachloride is varied by 0.005-0.05 unit proportionally to a variation in Currer plasticity by 0.01 unit. EFFECT: more efficient preparation process. 2 cl, 1 dwg, 2 tbl
