Abstract: An improved paper coating composition containing, per 100 parts by weight of finely divided pigment, from 5 to 25 parts by weight of a copolymer A having a glass transition temperature of from -40 DEG to +50 DEG C. in the form of an aqueous dispersion and from 0.1 to 10 parts by weight of a high molecular weight polymer B which is obtained by polymerizing water-soluble ethylenically unsaturated monomers in a water-in-oil emulsion. Papers having improved water resistance are obtained.

Abstract: O.Z. 0050/033151 A process for the preparation of PVP-iodine by reacting polyvinylpyrrolidone powder with elementary iodine at from 70 to 100.degree.C. The reaction is carried out in the presence of formic acid, oxalic acid or an ammonium salt or amide of carbonic acid, formic acid or oxalic acid. The process avoids the disadvantage of long periods of heating, which can result in degradation of the polyvinylpyrrolidone, and is particularly suitable for the preparation of an stable PVP-iodine using a low molecular weight polyvinylpyrrolidone.

Abstract: O.Z. 0050/032978 High molecular weight products based on N-vinylpyrrolidone, in which blocks of vinylpyrrolidone polymers or vinylpyrrolidone copolymers are linked by connecting units carrying ester, amide, urethane or urea groups, as a result of which these high molecular weight products are biodegradable and may be used as plasma substitutes, and the plasma substitutes thus obtained.

Abstract: A process for sizing staple fiber yarns by applying an aqueous sizing liquor which contains an alkaline earth metal salt of a copolymer containing from 90 to 30% by weight of acrylic acid and/or methacrylic acid and from 10 to 70% by weight of acrylonitrile and/or methacrylonitrile, which copolymer has a viscosity of from 50 to 1,000 cp in 15% strength aqueous solution at 85.degree.C, and drying the treated yarns. The sized films obtained are moistureinsensitive and have good heat stability.

Abstract: Mixtures of high molecular weigh polyacrylamides in the form of a water-in-oil polymer dispersion and containing in the inner phase from 99.99 to 95% w/w of a cationic polyacrylamide and from 0.01 to 5% w/w of an anionic polyacrylamide or from 99.99 to 95% w/w of an anionic polyacrylamide and from 0.01 to 5% w/w of a cationic polyacrylamide, all percentages being based on the total amount of polymer. The said polymer mixtures are particularly effective retention aids and flocculants and are preferably used in the manufacture of paper as pulp additives.

Abstract: Polyadducts, free from epoxide groups, are obtained from ammonia and epoxide compounds by reacting 1 mole of ammonia with from 1.2 to 2.0 equivalents of epoxide, so that if diepoxide compounds are used products of the general formula (I) are obtained, whilst if triepoxides and/or tetraepoxide compounds are used, by themselves, or together with diepoxide compounds, products of the general formula II (II) are produced; in these formulae, the E1's are identical or different hydroxyl-containing divalent radicals and the E2's are identical or different hydroxyl-containing trivalent or tetravalent radicals, resulting from the opening of the oxirane rings of epoxide compounds containing two, three or four epoxide groups in the molecule, n1, n3 and n5 are from 0 to 3, n2 and n4 are from 1 to 3 and X is 0 or 1, and one or more of the divalent radicals E1 in the general formula (II) may or may not be replaced by polyvalent radicals E2. The novel polyadducts can be modified by reaction with aldehydes, ketones, monoepoxide compounds, carboxylic acids, carboxylic acid esters or isocyanates, or by protonation with an acid, and may be used, for example, for the cathodic electrocoating of metallic articles.
