摘要 |
Branched, high molecular weight, thermoplastic polyarylene ethers which contain nitrile groups and are composed of repeating units of the formula I -E1-O-E2-O- where E1 is a radical derived from a dihalobenzene compound and E2 is a radical derived from a bisphenol, and contain from 0.01 to 5 mol %, based on the radical E1, of one or more radicals derived from polyhalo compounds of the formulae <IMAGE> (II) <IMAGE> (III) <IMAGE> (IV) <IMAGE> (V) <IMAGE> (VI) where X is fluorine or chlorine, and their preparation.
