摘要：
Aqueous suspensions of paints in waste waters can be treated to detackify the paint and facilitate its removal by contacting the paint suspension at a pH of from about 5 to about 14 with a polyarylamine that is produced by reacting an aldehyde with an arylamine in the presence of an acid in an aqueous suspension. The same polyarylamine can also be used for reducing the color content of highly colored liquids. Compositions containing the polyarylamine are also described.
