Abstract: A process for the preparation of polyaryl ether ketones by nucleophilic polycondensation of aromatic dihydroxyl compounds with aromatic dihalogen compounds using alkali metal carbonates and other alkali, alkaline earth and/or sub-group metal salts other than the alkali metal carbonates, where a) the alkali metal carbonates are employed in an excess of 0.5-10 Mol %, based on the amount of aromatic dihydroxyl compounds, and b) at least one other alkali, alkaline earth and/or sub-group metal salt is added at the beginning of the polycondensation in an amount corresponding at least to the molar excess of alkali metal carbonate.

Abstract: The polyaryl ether ketones are built up essentially from (A) 55 - 95 mol % of recurring units of the formula I or ring-substituted C1-C6-alkyl, C1-C6-alkoxy, aryl, chlorine or fluorine derivatives thereof, where s and t are each 0, 1, 2 or 3, and Q and T may each be -O- or -CO-, and (B) 5 - 45 mol % of recurring units of the formula II in which Ar , Ar , Ar , Ar and Ar , independently of one another, are each a phenylene, biphenylene or naphthylene group or a C1-C6-alkyl, C1-C6-alkoxy, aryl, chlorine or fluorine derivative thereof, Q' and T' may each be -O- or -CO-, and s' and t' are each 0, 1, 2 or 3, with the proviso that at least one of the substituents Ar , Ar , Ar , Ar and Ar is a biphenylene or naphthylene group or a C1-C6-alkyl, C1-C6-alkoxy, aryl, chlorine or fluorine derivative of such a group, and not all the parameters s, t, s' and t' are simultaneously 0 if Ar is a biphenylene group.
