    Abstract: 1,132,267. Electrolytic coating compositions. BADISCHE ANILIN- & SODA-FABRIK A.G. 25 Feb., 1966 [27 Feb., 1965], No. 8333/66. Headings C3P and C3R. [Also in Division C7] Aqueous solutions or dispersions of salts of bakable basic nitrogen cationic polymers used for electrophoretic coating) comprise on a weight basis a copolymer derived from, (1) 3 to 30% of aminoalkyl acrylates and/or methacrylates; (2) 3 to 30% of amides, N-alkylamides, N- hydroxyalkylamides and/or N-oxaalkylamides of acrylic and/or methacrylic acid; (3) 40 to 94% of alkyl acrylates and/or methacrylates and/or styrene and/or alkylvinyl benzenes; and (4) 0 to 30% of other copolymerizable ethylenically unsaturated monomers. Component (4) may be, for example, an hydroxyalkyl acrylate or methacrylate, an aliphatic vinyl carboxylate ester, acrylonitrile, methacrylonitrile, or a trialkylammoniumalkyl acrylate or methacrylate salt. Other watersoluble or water-dispersible binders capable of electrophoretic co-deposition with the copolymer salts may be added in an amount of 10 to 70% of said salts by weight, e.g. aminoplasts, phenoplasts, epoxide resins, alkyd resins or mixtures thereof. In one example an 8% solids solution of pH 4À5 is obtained by diluting the copolymer salt solution obtained by adding acetic acid to a solution formed by solution polymerization of mono - (N,N - diethylamine) - ethyl methacrylate, N-2-oxa-4-methylpentylamide of methacrylic acid, and n- and tert-butyl acrylates in n-butanol and p-xylene. In another example acrylamide is used instead of the above amide and 4-hydroxybutyl acrylate is also included, together with TiO 2 pigment and a watersoluble melamine- or phenol-formaldehyde resin. A further example employs a copolymer derived from γ - (N :N - diethylamino) - propyl acrylate, 2 - oxapropylacrylamide, 2 - ethylhexyl methacrylate, styrene, p-vinyl toluene and acrylonitrile.

    Abstract: Water-soluble polymers are made by polymerizing in aqueous solution one or more unsaturated compounds which individually or together are water-soluble and form water-soluble polymers, and then on to the resultant active polymer which has not been removed from its polymerization medium there are polymerized 0,5 to 30% by weight of the primary polymer of one or more unsaturated compounds which contain sulphonic acid and/or phosphonic acid radicals or radicals which yield sulphonic and/or phosphonic radicals after hydrolysis, until the second polymer formed has a K-value of at least 100 and wherein the quantity and nature of the monomers added to the primary polymer are such that the resulting product is water-soluble or water-solubilizable by hydrolysis. Monomers specified for use in forming the primary polymer are acrylic and methacrylic acids and their salts and amides, acrylic esters, acrylonitrile, vinyl pyrrolidone, styrene, vinyl methyl ketone, vinyl chloride and vinyl esters. Monomers specified containing sulphonic and phosphonic radicals are vinyl sulphonic acid, styrene monosulphonic and disulphonic acids, vinyl naphthalene sulphonic acid, vinylimidazole and vinylbenzimidazole sulphonic acids, reaction products of acrylyl or methacrylyl chloride with aminoalkylene sulphonic acids, cyanuric acid derivatives containing sulphonic acid groups and an acrylamide group, and corresponding compounds containing phosphonic acid radicals. The sulphonic or phosphonic acids may be used in the form of their salts or their esters or amides which are saponified after polymerization. Polymerization may be initiated by compounds such as azo-diisobutyramide, hydrogen peroxide and persulphates which may be activated with sulphites, hyposulphites, amines, ascorbic acid, cobaltous salts and ferrous salts. The examples describe processes in which: (1) acrylamide is polymerized in aqueous solution with the acid of potassium persulphate and formaldehyde sulphoxylate, followed by the polymerization in the same medium of sodium vinyl sulphonate; and (2) acrylamide is polymerized in aqueous solution with the aid of hydrogen peroxide and sodium sulphite, followed by the polymerization in the same medium of diethyl vinyl phosphonate with the subsequent hydrolysis of the product by heating in the aqueous medium.

    Abstract: Curable coating agents, a process for the production of scratch-resistant coatings on plastics, and articles coated by this process. The coating agents are polycondensates of a reaction product, containing two or more carbon-carbon double bonds and one or more hydroxyl or alkoxy groups per molecule, obtained from an olefinically unsaturated silane containing 2 or more hydroxyl or alkoxy groups, whose olefinically unsaturated organic radical is bonded via a C-Si bond, and a hydroxylcontaining .beta.,.beta.-olefinically unsaturated monomer, an olefinically unsaturated silane of the general formula R1-Si(OR2)3 where R1 is a vinyl radical or an alkyl acrylate or alkyl methacrylate radical bonded to the Si atom via a C-Si bond and R2 is hydrogen or a saturated hydrocarbon radical, and a saturated silane of the general formula where R3 and R4 are saturated or aromatic hydrocarbonradicals, with or without an epoxide-containing silane which also contains hydroxyl or alkoxy groups; the polycondensate may additionally contain an olefinically unsaturated reaction product of acrylic or methacrylic acid and a polyalcohol or polyether-ol. The costing agent is used to produce scratchresistant coatings on the surface of plastics.

    Abstract: 1,139,837. Aqueous compositions comprising an N-vinyl heterocyclic copolymer. BADISCHE ANILIN- & SODA-FABRIK A.G. 22 April, 1966 [24 April, 1965], No.17666/66. Heading C3P. [Also in Division C7] Coatings are produced on electrically conducting articles, e.g. of iron, copper or alloys thereof, metallized plastics or graphitized textile fabrics, by cataphoretic deposition from an aqueous solution or dispersion containing a salt of a copolymer derived from: (1) 3 to 50% by weight of a mono- or bicyclic compound having a 5- and/or 6-membered heterocycle containing 1 to 3 hetero atoms of which at least one is a basic N atom and one (which may be the same) is a N atom bearing a vinyl group, e.g. N-vinylimidazole, N - vinylpyrazole, N - vinylimidazoline, N - vinylpiperidine, N - vinylindole or N-vinyl-2-alkylimidazolines; (2) 3 to 30% by weight of an amide and/or N-(hydroxy or oxa) alkylamide of (meth)acrylic acid, e.g. acrylamide, or the N-methylamide, N-butylamide, N - methylolamide, N - 2 - oxahexylamide, N - 2 - oxapropylamide or N - 2 - oxa - 4 - methylpentylamide derivatives of acrylic acid; (3) 20 to 94% by weight of an alkyl ester of (meth)- acrylic and/or styrene and/or an alkylvinylbenzene, e.g. alkylstyrenes, or 2-ethyl-hexyl or butyl ester of acrylic acid and styrene; and (4) 0 to 30% by weight of one or more other ethylenically unsaturated monomer such as monohydroxyalkyl esters of (meth)acrylic acid having 2 to 6 C atoms in the alkyl group, or (meth)- acrylonitrile. The copolymers are preferably prepared by solution polymerization in organic solvents, e.g. methanol, ethanol, propanol, butanol, acetone, dioxane, tetrahydrofuran, or mixtures thereof with xylene, toluene or amyl acetate, prior to diluting with water. The salts may be produced by contacting the copolymers with acids such as HCl, H 2 SO 4 , H 3 PO 4 , formic or acetic acid or maleic anhydride. The aqueous solution or dispersion may also contain resin binders, o.g. aminoplast or phenoplast condensates, epoxy and/or alkyd resins, and pigments, e.g. TiO 2 . The coating is preferably baked, e.g. at 80-250‹ C.

    Abstract: A process for recovering water-soluble polymers in solid form from their highly viscous aqueous solutions comprises breaking up an aqueous solution of the polymer having a viscosity of at least 105 centipoises into small particles, introducing the latter into an organic liquid, which is substantially water-immiscible, to form a suspension of the polymer in the organic liquid, dehydrating the suspension by azeotropic distillation, and separating the suspended polymer particles from the organic liquid. Suitable organic liquids include heptane, carbon tetrachloride, tetrachloroethylene, amyl acetate, dibutyl ether, benzene, toluene, xylene and mixtures thereof. Suitable polymers include those of acrylamide, methacrylamide, acrylic acid, methacrylic acid, N-vinyl pyrrolidone, vinyl sulphonic acid, styrene sulphonic acid and N-vinyl imidazole, which compounds may possibly be copolymerized with, for example, acrylonitrile, methyl acrylate, vinyl acetate, vinyl chloride and, also, small amounts of crosslinking monomers. An example illustrates the recovery of an acrylamide/ammonium acrylate copolymer prepared by polymerizing the corresponding monomers in aqueous solution using an ammonium persulphate / sodium formaldehyde sulphoxylate catalyst.
