HETEROGENEOUS CATALYST COMPOSITION FOR POLYMERISATION OF ISOPRENE, METHOD FOR PRODUCTION AND USE THEREOF Russian patent published in 2015 - IPC C08F4/649 C08F4/65 C08F36/08 C08F2/00

Abstract RU 2569674 C2

FIELD: chemistry.

SUBSTANCE: said composition is a reaction product of the following three components: A) a titanium halide, B) an organoaluminium compound, primarily consisting of alkyl aluminium of general formula AlR₃, and C) an electron donor consisting of a polyether of general formula R⁰O(R¹O)_pR² (I) and/or a tetrahydrofurfuryl ether of general formula

(II).

Values of radicals R⁰, R¹, R² and R³ are given in the claim. The molar ratio of component B to component A is in the range of 0.01-10:1 and the molar ratio of component C to component B is in the range of 0.001-10:1. The invention also relates to a method of producing said heterogeneous catalyst composition and to a method of polymerising isoprene using said composition.

EFFECT: obtaining a catalyst for polymerisation of isoprene with high activity and improved properties of the obtained polymer.
