POLYMER DERIVATIVES FOR TREATING METALS |
摘要 |
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. |
