Abstract: Vinyl phosphonic acid and/or a salt thereof is polymerized alone or with other compounds containing one or more carbon-to-carbon double bonds and no halogen, using heat and/or irradiation with ultra-violet light and/or a radical-yielding catalyst. Comonomers specified are vinyl acetate, vinyl propionate, styrene, divinyl benzene, acrylic and methacrylic acids, esters, amides and nitriles, maleic acid mono and di-allyl esters, maleic anhydride, crotonic acid and esters, ethylene, propylene, butadiene, isoprene and mixtures thereof. In examples, vinyl phosphonic acid is polymerized alone, with a mixture of vinyl phosphonic acid diethyl ester and vinyl acetate, with acrylic acid, with styrene, with acrylonitrile, with methyl acrylate, and with methyl methacrylate while its monosodium salt is polymerized with vinyl acetate and with a mixture of vinyl acetate and dibutyl maleate. The catalysts lists are the usual peroxygen and redox ones and the polymerization may take place in bulk, solution or suspension. Specification 865,046 is referred to.

Abstract: A modified polyvinyl alcohol is prepared by subjecting a copolymer of a vinyl ester of a saturated carboxylic acid and an olefinically-unsaturated phosphonic acid dialkyl ester to alcoholysis with methanol and a mixture of methanol and methyl acetate, in the presence of 0 to 15 % water (calculated on the weight of copolymer) at 15 to 90 DEG C. until at least 80% of the ester groups are converted into vinyl alcohol groups. More than one ester may be present in the copolymer and the formate, propionate, butyrate, stearate and acetate are specified while other comonomers e.g. vinyl chloride, ethylene, isobutylene, and acrylic, methacrylic, maleic and fumaric esters. The phosphoric acid esters may be diesters of ethene-, propene-, or allyl-phosphonic acid. An alcoholysis catalyst e.g. sodium hydroxide, and alkali metal alcoholates or hydrochloric, perchloric, sulphuric, trichloroacetic and dodecyl benzenesulphonic acid may preferably be present.

Abstract: Copolymers are prepared by copolymerizing an ethylenically unsaturated monomer with an acyl urethane of the formula: R-CO-NH-CO-XR1 in which R-CO represents the radical of an unsaturated carboxylic acid which, in the case of a polycarboxylic acid, may additionally be esterified with a C1-C6 aliphatic alcohol or the other carboxyl groups of which may also be substituted by the carbamic acid radical -NH-CO-XR1, X represents oxygen or sulphur and R1 represents an alkyl radical containing up to 6 carbon atoms or a cycloalkyl, aryl or aralkyl radical, which radicals may be substituted. Acyl urethanes specified are isopropyl, butyl and beta-methoxyethyl N-acryloyl carbamates, beta-methoxyethyl N-crotonyl carbamate, the methyl ester of N-maleyl carbamic acid monobutyl ester and the butyl ester of N-maleyl carbamic acid monopropyl ester. Copolymerizable monomers specified are vinyl, allyl methallyl crotyl and propargyl esters of acetic, propionic, butyric, acrylic, methacrylic, crotonic, malonic, adipic, phthalic, maleic, citraconic itaconic and acetylene dicarboxylic acids, styrene and nuclear chloro-and methyl-styrenes, divinylbenzene, vinylcyclohexane, allylbenzene, allyl cyanostyrenes, alpha-substituted styrenes, vinyl pyridine, ethylvinyl ether, diallyl ether, hexyl vinyl ether, ethyl methallyl ether, methyl vinyl ketone, methyl allyl ketone, acrylamide, N-methyl acrylamide, N-methylol acrylamide, butadiene, chlorobutadiene, esters of butenediol, vinyl chloride and vinylidene chloride, ethyl methacrylate, methyl acrylate, dibutyl maleate and crotonamide. The polymers may be prepared by polymerization in bulk, solution or suspension. In the Examples: (1) butyl N-acryloyl carbamate and vinyl acetate are copolymerized in an aqueous solution of polyvinyl alcohol having a pH of 3 and containing hydrogen peroxide as an activator, (2) the same monomers as in (1) are copolymerized in an aqueous medium of pH 5-6 containing sodium dodecylbenzene sulphonate and sodium persulphate, the mixture of monomers being added gradually to the reaction medium, (3) methoxyethyl N-crotonyl carbamate and vinyl acetate are copolymerized as in (1) above, (5) butyl N-acryloyl carbamate, vinyl acetate and dibutyl maleate are copolymerized as in (1) above, (6) butyl N-acryloyl carbamate, crotonic acid and vinyl acetate are pearl polymerized with the aid of benzoyl peroxide in an aqueous medium containing the ammonium salt of a maleic acid-styrene copolymer; another copolymer which may be prepared in the same medium is that derived from a mixture of vinyl acetate, dibutyl maleate, crotonic acid and butyl N-acryloyl carbamate, (7) as in (2) but employing isopropyl N-acryloyl carbamate, and (8) acrylamide and methoxyethyl N-acryloyl carbamate are copolymerized in aqueous solution with the aid of a sodium persulphate/sodium metabisulphite mixture. The copolymers are applied to textiles in the form of aqueous solutions or dispersions or solutions in solvents such as aliphatic and aromatic hydrocarbons and chlorinated aliphatic hydrocarbons. Also present in the compositions may be precondensates of formaldehyde with urea or melamine, methylol compounds of cyclic urea derivatives, e.g. ethylene urea, and triazinones, precondensates of epoxy resins and acid donor substances, e.g. ammonium, magnesium and zinc salts. After application the compositions are dried by heating, e.g. to 60 DEG -180 DEG C. to render the coatings wash-fast.
