Abstract: Paper, board and cardboard are produced by draining a pulp slurry in the presence of high molecular weight, water-soluble polymers of N-vinylamides as drainage aids, retention agents and flocculants. These polymers are particularly effective in a pulp slurry which has a high content of interfering substances and other phenolic compounds.

Abstract: Use of copolymers obtainable by free-radical copolymerisation of (a) C8-C40-monoolefins with (b) ethylenically unsaturated C4-C8-dicarboxylic anhydrides in the manner of a mass polymerisation at from 80 to 300 DEG C to form copolymers having molecular weights of from 500 to 20,000 g/mol, subsequent solvolysis of the anhydride groups of the copolymers and at least partial neutralisation in an aqueous medium with bases of the carboxyl groups formed in the course of the solvolysis and which are present in the form of aqueous dispersions or solutions, as agents for waterproofing leathers and pelt furs.

Abstract: s Polyacetals useful as detergent additives contain units of the formula where R is hydrogen, C1-C4-alkyl or COOM, M is C1-C4-alkyl or an alkali metal, ammonium or alkanolamine group, and m is from 0 to 9, have K values (determined by the method of H. Fikentscher on the sodium salt in 1% strength by weight aqueous solution at 25.degree.C and pH 7) of at least 8.5, and are prepared by polymerizing compounds of the formula where R is hydrogen, C1-C4-alkyl or COOM, M is C1-C4-alkyl or an alkali metal, ammonium or alkanolamine group, R2 is C1-C4-alkyl, and m is from 0 to 9, in the presence of initiators and optionally comonomers with or without hydrolysis of the ester groups.
