Title:
PRODUCTION OF ISOBUTYLENE COPOLYMER DERIVATIVES
Document Type and Number:
WIPO Patent Application WO/2012/072536
Kind Code:
A3
Abstract:
Disclosed is the production of isobutylene copolymer derivatives by radically copolymerizing (a) 10 to 90 mol-% of a monoethylenically unsaturated C4 to C12 dicarboxylic acid or the anhydride, half-ester or full ester thereof, (b) 10 to 90 mol-% of a highly reactive isobutylene polymer having a number average molecular weight of 110 to 250,000, and (c) 0 to 50 mol-% of monoethylenically unsaturated compounds that can be copolymerized with monomer components (a) and (b), and then reacting the carboxylic acid or carboxylic acid derivative functions in the obtained isobutylene copolymer with ammonia, an amine and/or an alcohol so as to form groupings having hydroxy, carboxylic acid ester, amino, quaternized amino, amido and/or imido groups. In order to produce monomer component (b), isobutylene or a monomer mixture containing isobutylene is polymerized in the presence of an iron halide donor complex acting as a polymerization catalyst, an aluminum trihalide donor complex or an aluminum alkyl halide donor complex containing an organic compound having an ether function or a carboxylic acid ester function as a donor, or a Lewis acid complex containing at least one organic sulfonic acid and optional donors.
