摘要:
Polyarylene ethers which, based on the total amount of the structural units present in the polyether resin, contain 2-100 mol % of a recurring structural unit of formula I ##STR1## and 0-98 mol % of a recurring structural unit of formula II wherein each a is 1 or 2, 10 to 100% of X, based on the total number of the bonds X present in the structural units of formulae I and II, are --SO.sub.2 --, and 0 to 90% of X are --CO--, and A is a group of formula IIIa-IIIg: ##STR2## wherein Y is --CH.sub.2 --, --C(CH.sub.3).sub.2 --, --C(CF.sub.3).sub.2 --, --S--, --SO--, --SO.sub.2 --, --O-- or --CO--, and the aromatic rings in the structural units of formulae I and II are unsubstituted or substituted by one or more alkyl groups of 1 to 4 carbon atoms, have good solubility in organic solvents and are suitable preferably for modifying other plastics materials or for use as matrix resins for the production of fibrous composite structures.
