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.
