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 structural element (1) and at least three structural elements from a group comprising (2), (3), (4), (5); b) wat er or another solvent 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, the metal surface or plastic surface being brought into contact with a polymer (component A). Als o disclosed is the use of polymers (component A) to treat metal surfaces and separate metals or metal alloys from a plastic surface and polymers made of special components A'a, A'b, and A'c.

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.
