Abstract
Polyaryl sulphones containing repeating units -Ar-SO2- are obtained by polymerizing a compound of formula H-Ar-SO2.X and/or a mixture of compounds of formulae X.SO2-Ar-SO2X and H-Ar-H, where X is a halogen atom and Ar is a divalent aromatic radical, at a temperature up to 160 DEG C. in the presence of a Lewis acid catalyst and in solution in a nitrobenzene of formula <FORM:1109842/C3/1> where A1 is a hydrogen or halogen atom or an alkyl, cyano or nitro group and A2 is a hydrogen or halogen atom or an alkyl group. In at least some of the units of the polymer Ar is derived from a compound of formula <FORM:1109842/C3/2> (where Y is -O-, -S- or the residue of a 4,41-bisphenol) by the loss of a hydrogen atom from each benzene ring, and in any other units Ar is derived from benzene, biphenyl or an aromatic hydrocarbon containing not more than two aromatic nuclei. From 0.75 to 3 parts by weight of the nitrobenzene may be used per part by weight of polymerizable compounds. In examples polymers are obtained from diphenyl ether 4-sulphonyl chloride, from diphenyl ether and diphenyl ether 4,41-disulphonyl chloride, from 1,2-diphenoxyethane and diphenyl ether 4,41-disulphonyl chloride, from dibenzofuran and diphenyl ether 4,41-disulphonyl chloride, from dibenzofuran and diphenyl 4,41-disulphonyl chloride, and from diphenyl ether and diphenyl 4,41-disulphonyl chloride the monomers are dissolved in nitrobenzene and the catalysts are ferric chloride and antimony pentachloride.
