K-18546/A/CGM 389 Novel polyarylene ether ketones of the disclosure Polymers comprising 1-100 mol% of a recurring structural unit of the formula (Ia) or (Ib) (Ia), (Ib) and 99 - 0 mol% of a recurring structural unit of the formula (II) (II), in which Ar1 is one or more radicals of the formulae (IIIa) - (IIIi) (IIIa), (IIIb), (IIIc), (IIIb), (IIIe), (IIIf), (IIIg), (IIIh), (IIIi), in which Z is -CH2-, -C(CH3)2-, -C(CH3)(C6H5)-, -C(CF3)2-, -S-, -O-, -SO2, -SO2- or -CO-, Q is a direct bond, -CH2-, -O- or -CO-, and the radicals R1 to R4, independently of one another, are hydrogen or (C1-C4)alkyl, Ar2 is one or more radicals of the formulae (IVa) - (IVe) (IVa), (IVb), (IVc), (IVd), (IVe), in which X is -SO-, -SO2- or -CO-, a is the number O or 1, and b is the number 2 or 3, and in which the aromatic rings of the formulae (Ia), (Ib) and (IVa) - (IVe) are unsubstituted or substituted by one or more (C1-C4)alkyl groups, (C1-C4)alkoxy groups or (C6-Cl4)aryloxy groups, and in which the aromatic rings of the forrnulae (IIIa) - (IIIi) are unsubstituted or substituted by one or more (C1-C4)alkyl groups, (C1-C4)alkoxy groups, (C6-CI4)aryloxy groups or halogen atoms, have high thermal stability and are suitable for the production of mouldings, films or fibres, as matrix resins, adhesives or coating compositions, or as additives to other polymers.
