Abstract

Substantially abrasion-resistant cation exchange resins are prepared by sulphonating copolymers obtained by polymerizing one or more monovinyl aromatic compounds with one or more polyvinyl compounds and with vinyl or epoxy-group containing polymerizable polar compounds, the latter being present in amounts of 0.001 to 0.2 mol. per mol. of monovinyl aromatic compound or compounds, the polar compounds being different from the monovinyl and polyvinyl compounds. Monovinyl and polyvinyl compounds mentioned are styrene, vinyl-toluene, vinyl-ethyl-benzene, vinylanisole and divinyl-benzene, divinyl-ethyl-benzene, trivinyl-benzene, divinyl-acetylene, butadiene and divinyl ketone. Polar compounds mentioned are acrylic and methacrylic acids and their derivatives, especially acrylo- and methacrylo-nitriles, methylvinyl ketone and its homologues, vinyl halides, vinyl-benzene halides, methyl-vinyl ether and its homologues, vinylsulphonic acid and its derivatives, styrene-sulphonic acids and their derivatives, vinyl pyridine and its homologues, esters of vinyl alcohol such as vinyl acetate and propionate, maleic acid and its derivatives, styrene oxide, vinyl-toluene-oxide, ethyl-styrene oxide, ethylene and propylene oxides and epichlorohydrin. In the examples copolymers are produced from styrene and divinyl benzene with one of the following: methylmethacrylate, epichlorohydrin, methylvinylketone, acrylonitrile, methacrylic acid, maleic anhydride, propyl ester of styrene-sulphonic acid, ethyl acrylate, vinyl-sulphonic acid, vinyl pyridine, vinyl chloride or styrene oxide, in an aqueous suspension containing magnesium silicate, hydroxy-apatite, methyl-cellulose or magnesium hydroxide, the catalyst being diacetyl, dibenzoyl or dilauroyl peroxide or azo-bis-isobutyric acid nitrile. The copolymers which may first be swelled with a chlorinated hydrocarbon are sulphonated with sulphuric acid monohydrate, oleum, chlorosulphonic acid, oleum and chlorosulphonic acid or liquid sulphur trioxide.
