| abstract |
Copolymers of: (A1) 70 to 100 mol% of at least two different monoethylenically unsaturated carboxylic acid monomers and (A2) 0 to 30% of one or more non-ionic monomers, which have reacted with (B) 5 to 30 mol% , based on the amidatable functional groups present in the copolymers of the monomers (A1) and, if desired, (A2), of a C1-C2 aminoalkanesulfonic acid and / or a salt thereof, and the preparation of the copolymers and its use in detergents, cleaners and rinse aids. |
