Abstract
1,163,975. Polyarylsulphones. MINNESOTA MINING & MFG. CO. 7 Feb., 1967, No. 5896/67. Heading C3R. The invention comprises polymers having units of formula where Y is -0-, -S- or a direct bond and Z is -0-, -S- or The polymers are prepared from monomers having 2-sulphonyl halide groups by condensation with monomers having no sulphonyl halide groups, by selfcondensation of monomers having one sulphonyl halide group or by condensation of monomers having one sulphonyl halide group with other monomers. The condensation is carried out in a solvent in the presence of a Lewis acid as catalyst. In examples polymers are obtained from the mono-sulphonyl chlorides of 2-benzofuran, dibenzodioxin, fluorene, xanthene, dibenzo-1,4-thioxane, dibenzo-1,4-dithiane and thioxanthene.
