Abstract

Способ получения модифицированного цис-1,4-полиизопрена полимеризацией изопрена в присутствии катализатора, дезактивацией катализатора, стабилизацией и модификацией полимера азотсодержащим соединением с последующей дегазацией и сушкой выделенного полимера, заключающийся в том, что перед стадией дегазации в полимеризат вводят раствор технического алмазного углерода в количестве 0,005-0,1 масс % сухого вещества в расчете на полимер.A method of producing a modified cis-1,4-polyisoprene by polymerization of isoprene in the presence of a catalyst, catalyst deactivation, stabilization and modification of the polymer with a nitrogen-containing compound, followed by degassing and drying of the isolated polymer, which involves introducing a solution of technical diamond carbon in the amount of technical diamond carbon in an amount before the degassing step 0.005-0.1 wt% dry matter calculated on the polymer.
