METHOD OF PRODUCTION OF THE HIGHLY-ACTIVE POLYISOBUTENES Russian patent published in 2007 - IPC C08F10/10 C08F210/10 

FIELD: chemical industry; method of production of the highly-active polyisobutenes.

SUBSTANCE: the invention is pertaining to production of the highly active polyisobutenes. The A method of production highly-active homo- and interpolymers of isobutene with the contents of the tail vinyliden groups exceeding 80 molecular percent, and number-average molecular mass from 500 to 10000 Da by the cationic polymerization of isobutene or the isobutene with the monomers suitable for the copolymerization in the presence of the complexes of the stabilized in the dissolvent transition metal containing the weakly coordinated anions. The technical result consists in development of the economical method of production of the highly active polyisobutene at the temperatures exceeding 0°С.

EFFECT: the invention ensures development of the economical method of production of the highly active polyisobutene at the temperatures exceeding zero degree Celsius.
