Abstract
The invention relates to a method for reducing the negative effects of adhesive contaminants in the processing of waste paper, wherein an aqueous polymer dispersion comprising one component A and one component B for coagulation and detackification of stickies is added during the processing of waste paper, wherein component A is a homo- and/or copolymer of methyl methacrylate, acrylate and/or styrene and component B is a styrene copolymer having acrylic acid, maleimide and/or maleic acid hydride. The polymer dispersion can optionally comprise another component C, a cationic fixing agent that supports the coagulation of the stickies.
