METHOD FOR PRODUCTION OF SYNTHETIC POLYISOPRENE Russian patent published in 1996 - IPC

Abstract RU 2067983 C1

FIELD: production of synthetic polyisoprene rubber. SUBSTANCE: isoprene is polymerized on Ziegler-Natte catalyst, the process is followed by deactivation of said catalyst. At deactivation stage modifying agent is added, its quantity being 0.2-2.5 mass % as calculated for polymer. Chlorosulfonyl isocyanate is used as mentioned above modifying agent. EFFECT: improves efficiency of the method. 6 tbl
