Abstract

The invention relates to a process for fixing foreign substances in papermaking, wherein the agents used for fixing the foreign substances are polymers, consisting of cationic groups, of 50 to 100% by weight of quaternised dimethylaminopropylacrylamide or dimethylaminopropylmethacrylamide and 0 to 50% by weight of acrylamide, acrylic acid, methacrylic acid or acrylamidomethylpropanesulphonic acid, which have an intrinsic viscosity of less than 150 ml/g. The fixing agent is added to the pulp run and/or to the circulating water in quantities of up to 1% by weight relative to the dry weight of the paper produced.
