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: Water-soluble copolymers containing copolymerized vinylamine units are prepared by copolymerizing (a) from 95 to 10 mol % of N-vinylformamide and (b) from 5 to 90 mol % of an ethylenically unsaturated monomer from the group consisting of vinyl acetate, vinyl propionate, C1-C4-alkyl vinyl ethers, the esters, nitriles and amides of acrylic acid and methacrylic acid and N-vinylpyrrolidone, and then eliminating from 30 to 100 mol % of the formyl groups from the copolymer. Preferred copolymers are copolymers of N-vinylformamide and vinyl acetate, in which from 30 to 100 mol % of the monomer units are hydrolyzed. The copolymers are used in papermaking to increase the dry strength and wet strength of the paper.

Abstract: 1,200,216. Coated surfaces. BADISCHE ANILIN- & SODA-FABRIK A.G. 24 Nov., 1967 [26 Nov., 1966], No. 53500/67. Heading B2E. [Also in Division C3] Surfaces of wood, metal, concrete or glass are coated with a dispersion in an organic liquid of a copolymer of (a) a dye containing an olefinically unsaturated group, (b) an olefinically unsaturated monomer containing a nitrogen atom and at least one N-methylol or N-alkoxymethyl group, and (c) an olefinically unsaturated colourless commoner together with a copolymer of commoners (b) and (c). In the Example a coating of a dispersion of a copolymer of N-butoxyniethylmethacrylamide, ethyl acrylate, and a dye of formula where R is #-propoxyethyl, together with a copolymer of styrene, 2-ethyl-hexylacrylate, N- butoxymethylmethacrylamide and N-vinylimidazole in gasoline is coated on iron and cured at 140‹C. with 1 % of BF 3 .(C 2 H 5 )2O.
