Use of an acrylate copolymer as retention aid in a method of making a substrate comprising cellulosic fibres

The invention relates to the use of polyesters for increasing the surface tension and improving the hydrophilic behavior of hydrophobic surfaces, wherein said polyesters are obtainable by polymerization of

Polyester for the paper industry

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.
