    Abstract: In a process for the production of watersoluble salts of alpha, beta-ethylenically unsaturated sulphonic acids, beta-chlorethane sulphochloride or a beta chlorethane sulphochloride which is substituted in alpha- or beta-position is reacted in aqueous solution with an oxide, hydroxide or carbonate of a metal of Group IA or IIA or of magnesium or zinc oxide, lead oxide or copper oxide or an hydroxide or carbonate of ammonia. p Additional specific metal compounds referred to are sodium and potassium carbonates and hydroxides of lithium, sodium, potassium, magnesium, calcium and barium. The examples relate to the preparation of sodium, potassium, calcium, barium and ammonium vinyl sulphonates from beta-chlorethane sulphochloride. Alpha-or beta-position substituents which may be present in the starting materials include alkyl, halogen alkyl, aralkyl and aryl groups and additional starting materials specified include 1,3-dichlorpropane-2-sulphochloride, 1,2-dichlorpropane-3-sulpho-chloride, 2-chlorpropane-1-sulphochloride, 2,3-dichlorbutane-1-sulphochloride, 2,3-dichlorbutane-1,4-disulphochloride and 1-chlor-1-phenylethane sulphochloride. Specific metal hydroxides mentioned for use in the process include lithium, sodium, potassium, magnesium, calcium or barium pydroxide. The production of sodium, potassium, calcium, and barium vinyl sulphonates from beta-chlorethane sulphochloride is described.

    Abstract: Vinyl sulphonic esters are prepared by reacting b -chloroethene sulphochloride with at least two molar equivalents of an alcoholate of a metal of Periodic Group Ia or IIa, or at least one equivalent of an alcohol in the presence of at least two equivalents of a hydroxide of a metal of Group Ia, II, IIIa or IIIb, or ammonia or an amine, preferably dissolved or suspended in an organic solvent at a pH below 8, and separating the sulphonic acid ester from the chloride or hydrochloride. The b -chlorethane may be substituted in the a - or b -position by alkyl, halogenalkyl, aralkyl or aryl radicals, which may have 1 to 12 carbon atoms in the a - or b - position, e.g. 1,3-dichloropropane-2-sulphochloride, 1, 2 - dichlopropane - 3 - sulpho - chloride, 2-chloropropane-1-sulphochloride, 2,3-dichlorobutane-1-sulphochloride, and 1-chlor-1-phenylethane sulphochloride and the alcohols may be primary or secondary aliphatic, cycloaliphatic araliphatic or aliphatic-aromatic, linear or branched, monohydric or polyhydric, containing from 1 to 18 carbon atoms, for example, methanol, ethanol, propanol, butanol, hexanol, octanol, the corresponding iso-alcohols, cyclohexanol, ethylene glycol, glycerine, and benzyl alcohol. The alcoholates mentioned are those of lithium, sodium, potassium, magnesium and calcium, and the hydroxides which may be present are sodium, potassium, magnesium, calcium barium, zinc, cadmium, aluminium and ammonium and primary, sec- and t-amines are also tested. The reaction is carried out preferably at between -30 DEG C. and 20 DEG C. in an inert solvent, or in the alcohol or reaction product of the process, and inhibitors such as hydroquinone may be present. Free acid or salts may be obtained by saponification or alkaline saponification respectively. Examples describe the reaction of b -chloroethane sulphochloride with sodium methylate, sodium hydroxide dissolved in alcohol, and ammonia with methanol, ethanol, and butanol, to form the vinyl sulphonic acid methyl, ethyl and n-butyl esters.

    Abstract: Aqueous polymer suspension stable to frost and electrolytes are prepared by processes comprising polymerizing monomeric ethylenically unsaturated compounds in a aqueous media with water-soluble catalysts in the presence of 2 to 10%, by weight of the monomers, of an emulsifier which has a carbon chain of at least 6 carbon atoms, the hydrocarbon chain bearing a group containing at least one reactive hydrogen atom and which has been reacted with at least 5 mols of an alkylene oxide per mol and then sulphated, and adjusting the pH after polymerization to between 2 and 9. The monomer may be a conjugated diene, vinyl ester, vinyl ketone, vinyl ether, ethylene, styrene and its homologues, acrylic esters, acrylonitrile and their homologues, maleic and fumaric esters and nitrile, vinyl and vinylidene halides and vinyl lactams, optionally together with small amounts of acrylic acid, acrylamide and their homologues, vinyl pyrrolidone and vinyl imidazole. The catalyst may be a persulphate, hydrogen peroxide or peracetic acid, optionally together with sulphurous acid salts, alkylamines or hydroxyalkylamines. The emulsifiers may be prepared by reacting with ethylene or propylene oxide and sulphating fatty alcohols, fatty acids, resin acids, sulphuric acids, their amides and imides, monoalkylated and polyalkylated phenols and naphthols. Many suitable compounds are listed and examples describe the use of emulsifiers derived from sperm oil alcohol, coconut oil alcohol, decyl alcohol, C12-C18 alkyl sulphamides hexadecyl sulphamide of aminomethyl cyclohexane, octadecyl sulphamide, octadecyl sulphanilide, sperm oil acid monoethanolamide, octyl phenol, iso octyl phenol, ethyhexyl phenol, decyl phenol, iso decyl phenol, dodecyl phenol, octyl naphthol, decyl naphthol and dodecyl naphthol; and the copolymerization of methyl acrylate, methyl methacrylate and acrylic acid; ethyl acrylate, methyl methacrylate and acrylic acid; butyl acrylate, acrylonitrile and acrylic acid; vinyl propionate and butyl acrylate; vinylidene chloride, methylacrylate and acrylic acid; vinyl propionate, methyl methacrylate and acrylic acid; styrene, butyl acrylate and acrylic acid; butyl acrylate, methacrylamide, acrylic acid and vinyl chloride; butyl acrylate and vinyl acetate; vinyl propionate and dimethyl maleate; and methyl acrylate, acrylonitrile and acrylic acid. The dispersions may be used for coating and making films, treating leather and textiles, and in floor coverings.
