摘要： 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.

摘要： The present invention relates to polyester that can be obtained by polymerization of a) terephtalacid dimethylester, and b) ethylene glycol, and c) 1,2-propylene glycol, and d) one or a plurality of polyethylene glycols having weight average molecular weights in the range of 1,000 to 2,000 g/mol, and e) one methyl polyethylene glycol having a weight average molecular weight in the range of 1,050 to 1,350 g/mol, f) either when a plurality of compounds having a reticulating effect and 3 to 6 functions that are enabled for polycondensation are present or absent. The polyester according to the invention can be used in an advantageous manner, e.g. to modify hydrophobic surfaces, which can be used, e.g., in paper recycling.
