    Abstract: 1,159,812. Electrolytic polymer coating compositions. BADISCHE ANILIN- & SODAFABRIK A.G. 8 July, 1966 [9 July, 1965], No. 30710/66. Heading C3P. [Also in Division C7] A solution of a copolymer for cathodic deposition on a conducting substrate comprises on a weight basis a copolymer prepared by solution polymerization of 10 parts N-1-(N 1 :N 1 - dimethylamino)-propyl-(3)-amide of acrylic acid, 20 parts N-2-oxa-4-methylpentylamide of methacrylic acid, 20 parts methyl methacrylate, and 50 parts tert-butyl acrylate in 100 parts of a 1: 1 mixture of n-butanol and p-xylene, diluted with water to a solids content of 8 % and adjusted to pH 6 with acetic acid. Another composition suitable for cathodic deposition comprises a copolymer prepared by solution polymerization of 10 parts N-1-(N 1 :N 1 - dimethylamino)-propyl-(3)-amide of acrylic acid, 5 parts acrylamide, 40 parts n-butyl acrylate, 35 parts tert-butyl acrylate, and 10 parts 4- hydroxybutyl acrylate in 100 parts of a 1: 1 mixture of n-butanol and p-xylene to which copolymer is added 0À5 mole acetic acid per mole of the substituted acrylic acid amide, the resultant salt being admixed in a solids ratio of 90: 10 with a water-soluble melamine-formaldehyde resin partly etherified with methanol and the mixture being diluted with water, 13 parts TiO 2 pigment added and the resultant mix homogenized by ball-milling, followed by dilution with water to 8% solids content. A further suitable copolymer salt is produced from maleic acid and a copolymer prepared by copolymerization of 3 parts N- aminoethyl acrylamide, 8 parts N: N-di-(N 1 :N 1 -diethylamino)ethylamide of acrylic acid, 3 parts N- ethyl methacrylamide. 4 parts N-methylol methacrylamide, 35 parts styrene, 30 parts n-butyl acrylate, 10 parts tert-butyl acrylate, 5 parts acrylonitrile, and 3 parts N-vinylimidazole.

    Abstract: Sizing fibres formed of cellulose and/or polyacrylonitrile or contng. at least 30% of these fibres by deposition of an aqs. sizing bath contng. a copolymer of (a) acrylonitrile and (b) acrylic acid or sodium or ammonium acrylate contng. (a) and (b) in mol. ratio 1 : 1.5 to 1 : 7, pref. 1 : 2-1 : 6, and in 10% aqs. soln. at 20 deg.C., having viscosity 20-2000 cP. pref. 250-2000 cP. and pH 2.5-6.5, pref. 3-5.5. The polymers dissolve readily in water and the sizing baths can be produced in cold water with moderate stirring. There is no loss by evaporation during application and the polymers give similar or improved effects in smaller amounts than normal sizes, e.g. improved abrasion resistance. The baths are stable and can be kept for several weeks, and the sizes are readily removed by washing.
