Mischungen aus Polymerisaten von monoethylenisch ungesättigten Dicarbonsäuren und Polymerisaten ethylenisch ungesättigter Monocarbonsäuren und/oder Polyaminocarbonsäuren und ihre Verwendung

摘要

The invention concerns mixtures of (I) polymers of monoethylenically unsaturated dicarboxylic acids with a molecular weight of 200 to 5,000 and (II) (1) copolymers with a molecular weight of 10,000 to 150,000 consisting of (a) 10 to 70 % by wt. of monoethylenically unsaturated C4 to C8 dicarboxylic acids or salts thereof and (b) 30 to 90 % by wt. of monoethylenically unsaturated C3 to C10 monocarboxylic acids and/or salts thereof, (2) homopolymers and copolymers with a molecular weight of 1,000 to 500,00 consisting of monoethylenically unsaturated C3 to C10 monocarboxylic acids, (3) graft polymers with a molecular weight of 5,000 to 150,000 obtained by the radical-initiated graft polymerization of (A) monoethylenically unsaturated C3 to C10 carboxylic acids, their anhydrides and/or their salts in the presence of (B) mono-, oligo- or polysaccharides derivatives thereof, in the ratio by weight of A:B of (95 to 100):(5 to 80) and/or (4) polyaminocarboxylic acids and/or polymers containing aminocarboxylic groups, the mixtures containing components (I) and (II) in the ratio by weight of 10:0.5 to 0.5:10. The invention also concerns the use of such mixtures as additives in phosphate-free or phosphate-reduced textile-washing agents or as dispersants and deposit-prevention agents in cleaning agents for hard surfaces.
