Title:
四級化コポリマー
Document Type and Number:
Japanese Patent JP2013531097
Kind Code:
A
Abstract:
The invention relates to a quaternized copolymer, which can be obtained by: (A) copolymerizing straight-chain, branched or cyclic ethylenically unsaturated C2 to C100 hydrocarbons, which can bear oxygen-functional or nitrogen-functional substituents which cannot be reacted with amines to obtain amides or imides, or with alcohols to obtain esters, with ethylenically unsaturated C3- to C12-monocarboxylic acids or -dicarboxylic acids, or derivatives thereof, which can be reacted with amines to obtain amides or imides, or with alcohols to obtain esters, to obtain a copolymer having a number average molecular weight of 500 to 20,000; (B) partially or fully amidating or imidating or esterifying the carboxylic acid functions by reaction with oligoamines having 2 to 6 nitrogen atoms or alcohol amines, which each contain a primary or secondary nitrogen atom or a hydroxyl group and a quaternizable tertiary nitrogen atom; (C) partially or fully quaternizing the tertiary nitrogen atom with a quaternizing agent. The quaternized copolymer thus produced is suitable as a fuel additive in direct-injection diesel engines.
