High-temperature-resistant, thermoplastically processable polyarylene ethers with repeating structural units of the general formula wherein A represents 4,4'- or 4,4"-benzophenone units of the formula with z being O or 1, B represents 9,9-bis(4'-phenyl)fluorene units of the formula and C represents 2,2-bis(4-phenyl)propane units of the formula which are linked to one another in etherlike fashion through oxygen atoms, the composition of the polyarylene ethers being determined by m and n, the molar ratio of which ranges from 30:70 to 90:10, and wherein the sequence of the segments containing B or C may be random. |
