Abstract: Paper, board and cardboard are produced by draining a paper stock, containing un- desirable substances, in the presence of hydrolyzed homo- and/or copolymers of N-vinylformamide having a degree of hydrolysis of not less than 60% and a cationic retention aid. According to the invention, faster drainage and improved retention are obtained compared with the use of known fixing agents.

Abstract: The invention concerns aqueous alkyldiketene dispersions containing an alkyldiketene, cationic starch with an amylopectin content of at least 95 % by wt. and the following anionic dispersants: (a) 0.05 to 1 .0 % by wt. of lignin sulphonic acid, condensation products of naphtalene sulphonic acid and formaldehyde, sulphonated polystyrene or salts or mixtures of such polymers and (b) 0.05 to 1.5 % by wt. of sulphuric acid half esters of alcohols with at least 10 C-atoms, mono- or diphosphoric acid half esters of alkoxylated alcohols with at least C-atoms, sulphuric acid half esters of alkoxylated alcohols with at least 10 C- atoms, mono- or diphosphoric acid esters of alkoxylated alcohols with at least 10 C-atoms, C12-C30 alkyl sulphonic acids or salts or mixtures of such compounds. The invention also concerns the use of such alkyldiketene dispersions as bulk size in the manufacture of paper, paperboard and cardboard, as well as in making cellulose fibres water-repellent.

Abstract: Paper, board and cardboard having high dry strength are produced by the addition of cationic, anionic and/or amphoteric starch as dry strength agents to the paper stock and drainage of the paper stock with sheet formation in the presence of cationic polymers as retention aids for starch, and cationic polymeric retention aids are used for increasing the retention of dry strength agents comprising cationic, anionic and/or amphoteric starch in the production of paper, board and cardboard.
