Polyarylene ethers containing tetraphenylethylene units Abstract Polyarylene ethers which contain, based on the total amount of structural elements present in the polymer, 2-100 mol% of one or more recurring structural elements of the formula Ia, Ib or Ic (Ia), (Ib), (Ic) and 0-98 mol% of a recurring structural element of the formula II (II) in which Ar1 and Ar2 are, for example, 4,4'-diphenyl sulfone radicals, have very good solubility in a wide range of organic solvents and can be processed from these stable solutions. |
