METHOD FOR PRODUCTION OF MODIFIED CIS-1,4-POLYISOPRENE Russian patent published in 2006 - IPC C08F36/06 C08F136/06 C08C19/22 

Abstract RU 2281295 C1

FIELD: polymers, rubber industry, in particular production of stereoblock polymers of conjugated dienes, such as cis-1,4-polyisoprene.

SUBSTANCE: modified cis-1,4-polyisoprene is obtained by polymerization pf isoprene in isopentane medium in presence of Ziegler-Natta catalyst. Then catalyst is deactivated; polymer is stabilized and modified with nitrogen-containing compound; polymer in isolated and dried. As nitrogen-containing compound reaction product of maleic anhydride and N-alkyl-N'-phenyl-n-phenylenediamine in amount of 0.5-2 % based on polymer is used.

EFFECT: simplified method for production of polymers having heat oxidative stability.
