Abstract

Cross-linked copolymers suitable for use as cation exchange resins are prepared by a process which comprises polymerizing in the presence of a polymerization catalyst a mixture comprising (1) acrylonitrile, (2) acrylic or methacrylic acid, an ester of acrylic or methacrylic acid, or a mixture of acrylic or methacrylic acid with an ester thereof and (3) commercially available divinyl benzene, saponifying the ester groups under mild conditions where the copolymers contain no carboxyl groups, heating the copolymers at 150 to 200 DEG C. to effect condensation of the carboxyl and nitrile groups, and if necessary saponifying under strong conditions to convert the nitrile and/or ester groups still present in the polymer to carboxyl groups. The catalyst may be benzoyl peroxide. Polymerization may be effected in aqueous suspension or in bulk, the product being ground or milled to the required granular size. Examples describe (I) the copolumerization of acrylonitrile, acrylic acid and divinyl benzene and (V) the heating of the product and saponification with hot concentrated sodium hydroxide solution; (II) the copolymerization of ethyl acrylate, acrylonitrile and divinylbenzene and (VI) the saponification of the ester groups with dilute sodium hydroxide solution and the heating of the product; and (III) the copolymerization of methyl acrylate, acrylonitrile, acrylic acid and divinylbenzene and (VII) the heating and saponification of the product. The saponified products are useful as cation exchange resins.
