Abstract (en)
[origin: US2007238637A1] The present invention relates to a process for preparing granular or pulverulent detergent compositions, comprising the preparation of a detergent base powder by drying an aqueous detergent slurry, which comprises adding to the slurry a copolymer which is obtainable by free-radical copolymerization of (A) from 50 to 99.5 mol % of a monoethylenically unsaturated monocarboxylic acid and/or a salt thereof, (B) from 0.5 to 20 mol % of an alkoxylated monoethylenically unsaturated monomer I in which the variables are defined as follows: R<SUP>1 </SUP>is hydrogen or methyl; R<SUP>2 </SUP>is -(CH<SUB>2</SUB>)<SUB>x</SUB>-O-, -CH<SUB>2</SUB>-NR<SUP>5</SUP>-, -CH<SUB>2</SUB>-O-CH<SUB>2</SUB>-CR<SUP>6</SUP>R<SUP>7</SUP>-CH<SUB>2</SUB>-O- or -CONH-; R<SUP>3 </SUP>are each identical or different C<SUB>2</SUB>-C<SUB>4</SUB>-alkylene radicals which may be arranged blockwise or randomly, the proportion of ethylene radicals being at least 50 mol %; R<SUP>4 </SUP>is hydrogen, C<SUB>1</SUB>-C<SUB>4</SUB>-alkyl, -SO<SUB>3</SUB>M or -PO<SUB>3</SUB>M<SUB>2</SUB>; R<SUP>5 </SUP>is hydrogen or -CH<SUB>2</SUB>-CR<SUP>1</SUP>-CH<SUB>2</SUB>; R<SUP>6 </SUP>is -O-[R<SUP>3</SUP>-O]<SUB>n</SUB>-R<SUP>4</SUP>, where the -[R<SUP>3</SUP>-O]<SUB>n</SUB>- radicals may be different from the further -[R<SUP>3</SUP>-O]<SUB>n</SUB>- radicals present in formula I; R<SUP>7 </SUP>is hydrogen or ethyl; M is alkali metal or hydrogen; n is from 4 to 250; x is 0 or 1, (C) from 0 to 50 mol % of a monoethylenically unsaturated dicarboxyic acid, of an anhydride and/or of a salt thereof and (D) from 0 to 20 mol % of a further copolymerizable monoethylenically unsaturated monomer and has an average molecular weight M<SUB>w </SUB>of from 30 000 to 500 000 g/mol and a K value of from 40 to 150 (measured at pH 7 in 1% by weight aqueous solution at 25° C.).
