Abstract (en)

[origin: WO2005042684A1] The invention relates to the use of copolymers which contain alkylene oxide units, as deposit inhibitor additives in the rinsing process of a dishwasher, said copolymers containing the following constituents, incorporated by block or statistical polymerisation: (a) 50 to 93 mol% of acrylic acid and/or a water-soluble salt thereof, (b) 5 to 30 mol% of methacrylic acid and/or a water-soluble salt thereof and (c) 2 to 20 mol% of at least one non-ionic monomer of formula (I), wherein the variables have the following meaning: R<1> = hydrogen or methyl; R<2> represents a chemical bond, or branched or unbranched C1-C6 alkylene; R<3> represents identical or different, branched or unbranched C2-C4 alkylene radicals; R<4> represents branched or unbranched C1-C6 alkyl and n = 3 to 50.
