Abstract: A process for preparation of paper, pasteboard, or cardboard involving cutting of the paper pulp, addition of microparticles of cationic polymer, and a finely divided inorganic component after the last cutting step and before pulp swelling, dewatering of the pulp, and sheet formation and drying of the sheets is new. A process for preparation of paper, pasteboard, or cardboard involving cutting of the paper pulp, addition of microparticles of cationic polymer, and a finely divided inorganic component after the last cutting step and before pulp swelling, dewatering of the pulp, and sheet formation and drying of the sheets. The cationic polymer of the microparticle system is cationic polyacrylamide, polymer containing vinylamine units, and/or polydiallyl dimethylammonium chloride containing polymer of mean mol.wt. 500,000 Dalton, and maximum charge density 4.0 meq/g, where the microparticle system free from polymers of charging density (sic) more than 4 meq/g is used as the retention agent.

Abstract: Aqueous dispersions of water-soluble polymers of N-vinylcarboxamides, which contain, as a stabilizer, water-soluble, crosslinked graft polymers which are obtainable by free radical polymerization of compounds having at least two ethylenically unsaturated double bonds in the presence of polyalkylene glycols, are prepared by free radical polymerization of N-vinylcarboxamides in an aqueous medium in the presence of said stabilizers and are used as drainage aids, flocculants and retention aids, as wet and dry strength agents and as fixing agents in papermaking.
