摘要：
Use of copolymers containing alkylene oxide units which comprise (a) 50 to 93 mol % of acrylic acid and/or a water-soluble salt of acrylic acid, (b) 5 to 30 mol % of methacrylic acid and/or a water-soluble salt of methacrylic acid and (c) 2 to 20 mol % of at least one nonionic monomer of formula I in which the variables have the following meanings: R1 is hydrogen or methyl; R2 is a chemical bond or unbranched or branched C1-C6-alkylene; R3 are identical or different unbranched or branched C2-C4-alkylene radicals; R4 is unbranched or branched C1-C6-alkyl; n is 3 to 50, in random or block copolymerized form, as additive for detergents and cleaners.
