Title:
METHOD FOR PRODUCING HOMOPOLYMERS AND COPOLYMERS OF ISOBUTENE
Document Type and Number:
WIPO Patent Application WO2002048216
Kind Code:
A3
Abstract:
The invention relates to a polymerization method for isobutene or mixtures of isobutene with ethylenically unsaturated comonomers under the conditions of a living cationic polymerization . According to the invention, the initiator system additionally comprises at least one non-polymerizable aprotic silicon-organic compound having at least one Si-O bond.
