Title:
ポリアルキレンオキシド基および四級化窒素原子を含有するコポリマー
Document Type and Number:
Japanese Patent JP4427550
Kind Code:
B2
Abstract:
Copolymers which comprise in copolymerized form, (A) 60 to 99% by weight of at least one monoethylenically unsaturated polyalkylene oxide monomer of the formula I H2C-CR1-X-Y![private use character Parenopenst]()
-R2-O-![private use character Parenclosest]()
n-R3 I in which the variables have the following meanings: X is -CH2- or -CO-, if Y is -O-; is -CO-, if Y is -NH-; Y is -O- or -NH-; R1 is hydrogen or methyl; R2 are identical or different C2-C6-alkylene radicals, which may be linear or branched and may be arranged blockwise or randomly; R3 is hydrogen or C1-C4-alkyl; n is an integer from 3 to 50, (B) 1 to 40% by weight of at least one quaternized nitrogen-containing monoethylenically unsaturated monomer, (C) 0 to 39% by weight of anionic monoethylenically unsaturated monomers and (D) 0 to 30% by weight of other nonionic monoethylenically unsaturated monomers and have an average molecular weight Mw of from 2000 to 100 000, and use of these copolymers as dispersants for clay minerals.
