    Abstract: 1316590 Unsaturated sulphito-betaines BADISCHE ANILIN- & SODA-FABRIK AG 18 Sept 1970 [20 Sept 1969] 44628/70 Heading C2C [Also in Division C3] The invention comprises olefinically unsaturated sulphito-betaines, particularly those having the formula where X is -O- or -NH-, R 1 is an optionally substituted vinyl group, R 2 and R 3 each represent an alkyl group or together with the linking N atom form a heterocyclic ring which optionally contains at least one further hetero atom, R 4 is H, a phenyl radical, a carbamoyl radical, or an alkyl or alkenyl radical having up to 4 C atoms and optionally substituted by a halogen atom, an amido group, an epoxy group or a phenyl radical, and n is an integer from 1 to 18. The moiety R 1 -COX- is preferably an acyloxy or acylamino radical derived from an olefinically unsaturated monocarboxylic acid or dicarboxylic acid having 3-5 carbon atoms (e.g. acrylic, methacrylic, maleic, fumaric or itaconic acid). The sulphitobetaines can be prepared by reacting (a) equimolar amounts of sulphur dioxide and an alkylene oxide with (b) an olefinically unsaturated tertiary amine.

    Abstract: 1412203 Emulsion polymerization BADISCHE ANILIN- & SODA-FABRIK AG 23 Feb 1973 [25 Feb 1972] 8941/73 Heading C3P The emulsion polymerization of ethylenically unsaturated monomers is effected using as emulsifier a sulphonium salt of the formula in which X is hydrogen or methyl and R 1 to R 3 are #-hydroxyalkyl, alkyl or aralkyl groups containing a total of 10-25 carbons provided at least one is #-hydroxyalkyl, or an oxidation product of such a sulphonium salt. In examples the following monomers are copolymerized (1) vinylidene chloride/ethyl acrylate, (2) nbutyl acrylate / acrylonitrile / styrene / N,N- dimethyl aminoethyl acrylate (in sulphuric acid) and (3) vinylidene chloride/n-butyl acrylate / N - vinyl - N - methylimidazolium methosulphate.
