Abstract: Paper and paperboard of high dry strength are produced by adding a dry strength enhancer to the paper stock and dewatering the paper stock with sheet formation by using as the dry strength enhancer a mixture of a cationic polymer which contains as characteristic monomers copolymerized units of (a) diallyldimethylammonium chloride, (b) N-vinylamine or (c) a substituted or unsubstituted N-vinylimidazoline and has a K value of not less than 30, and natural potato starch which is converted into a water-soluble form by heating in an aqueous medium at above the gelatinization temperature of natural potato starch in the absence of any oxidizing agents or alkali.

Abstract: Polymers of olefinically unsaturated monomers and solutions of polymers of olefinically unsaturated monomers obtainable by polymerising the olefinically unsaturated monomers in the presence of free radical-forming initiators in solution under otherwise prespecified polymerisation conditions in a process in which a solvent and/or a liquid part of one or more reaction components of the polymerisation batch is initially introduced and heated to the polymerisation temperature, and, while maintaining or initiating the polymerisation, some or all of the monomers to be polymerised are fed continuously, via at least one feed, to the initially introduced part of the polymerisation batch (which is kept in motion), in such a manner that the exit opening of the at least one feed is above the surface of the initially introduced liquid part of the polymerisation batch.
