    Abstract: Polymers of a poly(meth)acrylic acid main chain in which, based on the main chain, 0 to 30% by weight of the (meth)acrylic acid basic building blocks may be replaced by maleic acid (anhydride) basic building blocks, fumaric acid basic building blocks or mixtures thereof and 0 to 10% by weight of the (meth)acrylic acid basic building blocks may be replaced by other copolymerizable ethylenic basic building blocks,and C1-30-alkylpoly-C2-4-alkylene glycols, bonded to the main chain via ester groups, having an average molecular weight of from 250 to 10 000 as side chains,where, based on the polymer, 1 to 19% by weight of the main chain and 81 to 99% by weight of the side chains are present and this ratio and the average molecular weight of the side chains are chosen such that free carboxyl groups are present in the polymer,are used as controllable dispersants for detergents or cleaners or constituents thereof.

    Abstract: A composition for the treatment of metal surfaces and for the deposition of metals or metal alloys on plastics surfaces contains a) at least one polymer as component A, composed of the structural element (1) and at least three structural elements selected from the group consisting of b) water or another solvent which is suitable for dissolving, dispersing, suspending or emulsifying the polymer, as component B; c) if required, surface-active compounds, dispersants, suspending media and/or emulsifiers as component C. In a process for the treatment of a metal surface and a process for the deposition of metals or metal alloys on a plastics surface, the metal or plastics surface is brought into contact with a polymer (component A). Furthermore, polymers (component A) are used for the treatment of metal surfaces and for the deposition of metals or metal alloys on a plastics surface, and polymers composed of special components A'a, A'b and A'c.

    Abstract: The invention relates to a composition for treating metal surfaces and for separating metals or metal alloys from plastic surfaces, containing: a) at least one polymer as component A, made of a polymer containing amino groups (component Aa), at least one aromatic compound (component Ab), and optional aldehyde (component Ac); b) water or another solving agent suitable to solve, disperse, suspend, or emulsify the polymer as component B; c) optional surface-active compounds, dispersing agents, suspending agents, and/or emulsifiers as component C. The invention also relates to a method for treating a metal surface and a method for separating metals or metal alloys from a plastic surface, whereby the metal surface or plastic surface is brought into contact with a polymer (component A). Also disclosed are the use of polymers (component A) for treating metal surfaces and for separating metals or metal alloys from a plastic surface and polymers made of special components A'a, A'b, and A'c.
