Abstract

A solid unfractured cation-exchange resin having at least two dimensions each in excess of one cm. comprises a three-dimensional crosslinked polymer matrix bonded to cation-exchange groups, the matrix being formed by polymerization of a solution of (1) at least one monovinyl aryl compound; (2) a polymer of (1) in amount of at least 0.1 per cent of (1); and (3) at least one polyvinyl aryl and/or polyolefinic compound, the cation-exchange groups being formed on the matrix by sulphonation. Specified monovinyl aryl compounds are styrene alpha- and ar-methylstyrene, ar-dimethyl- and ar-chloro-styrene, ar-ethylvinylbenzene, vinyl naphthalene, ar-methylvinylnaphthalene, ar-sec.-butyl and ar-trimethyl-styrene and specified polyvinyl compounds are di- and trivinylbenzenes, divinylnaphthalene, ar-divinyl, toluene and -xylene, ar-divinylchlorobenzene, ar-divinylethyl benzene and divinylether, while specified polyolefinic compounds are butadiene, isoprene, dimethallyl, diallyl, and cyclopentadiene. It is preferred that the monovinyl aryl compound constitutes more than 10 per cent, and the polyvinyl aryl or polyolefinic compound less than 50 per cent of the solution while the polymepic product may be prepared by polymerizing 0.1 to 60 per cent of the monovinyl aryl compound. A plasticizer, e.g. dimethyl phthalate, may be added at any time during the preparation of the matrix, which may also incorporate non-polymerizable reinforcing material, e.g. glass fibres. The polymerization may take place in the presence of a catalyst, e.g. benzoyl, lauroyl or hydrogen peroxide, potassium or ammonium persulphate and sodium perborate, and in bulk or solution. The sulphonating agent may be sulphuric acid, oleum, chlorosulphonic acid, anhydrous sulphuric acid or sulphur trioxide and the sulphonation may be preceded by a swelling operation using as a swelling agent benzene, toluene, xylene, isopropylbenzene, chlorbenzene, tetrachloroethane or trichloroethylene. U.S.A. Specifications 2,366,007, 2,466,675, 2,500,149 and 2,597,438 are referred to.
