K-17497/+/CGM 347 Novel polyarylene ethers Abstract The invention relates to polyarylene ethers which contain, based on the total amount of structural elements present in the polyether resin, 5-100 mol% of a recurring structural element of the formula I Image (I) and 0-95 mol% of a recurring structural element of the formula II Image (II) in which X and X' independently of one another are -SO-, -SO2- or -CO-, one of the radicals R1, R2, R3 and R4 is phenyl or phenyl which is substituted by one to three (C1-C4)alkyl groups and the remaining radicals R1, R2, R3 and R4 independently of one another are hydrogen, (C1-C4)alkyl, phenyl or phenyl which is substituted by one to three (C1-C4)alkyl groups, and A is an aromatic radical, at least 25 % of the bonds X and/or Y and/or the bridge members contained in A being -SO2-. These industrial materials are distinguished by very good mechanical properties and good solubility.
