Moulding compositions based on polyarylene ethers A containing anhydride terminal groups and recurring units I <IMAGE> in which t and q are each an integer 0, 1, 2 or 3, T, Q and Z are each a chemical bond or a group selected from -O-, -S-, -SO2-, S=O, C=O, -N=N-, -R<a>C=CR<b>- and -CR<c>R<d>-, with the proviso that at least one of the groups T, Q and Z is -SO2- or C = O, R<a> and R<b> are each a hydrogen atom or a C1- to C10-alkyl group, R<c> and R<d> are each a hydrogen atom, a C1- to C10-alkyl group, a C1- to C10-alkoxy group or a C6- to C18-aryl group, where the above groups may each be substituted by fluorine and/or chlorine atoms, Ar and Ar<1> are C6- to C18-aryl groups, it being possible for these to have substituents selected from C1- to C10-alkyl, C6- to C18-aryl, C1- to C10-alkoxy and halogen, or their random copolymers or block copolymers.
