Abstract (en)
[origin: CA2780687A1] The invention relates to a method for producing paper or the like, wherein cationic polymer microparticles composed of polyacrylamide and a fine-particle, inorganic component are added to the paper material after the last shearing step and before the headbox, whereupon the paper material is subjected to drainage in order to form sheets and the sheets are subjected to drying. In addition, a polymer mixture, which is composed of a linear, cationic polymer and a linear, anionic copolymer, and the overall ionicity of which is anionic, is added immediately before the headbox.
