Highly heat-resistant polyaryl ether ketones are composed of (A) from 50 to 100 mol % of repeat units of the general formula I <IMAGE> I <IMAGE> or a ring-substituted C1-C8-alkyl, C1-C8-alkoxy, aryl, chlorine or fluorine derivative thereof and (B) from 0 to 50 mol % of repeat units, different from I, of the general formulae II and/or III <IMAGE> II <IMAGE> III <IMAGE> or a ring-substituted C1-C8-alkyl, C1-C8-alkoxy, aryl, chlorine or fluorine derivative thereof, where Q, Q', Y, Y', T, T', Z and Z' are each -O-, -CO- or a chemical bond, one or more of these substituents is a -CO- group, and s, t and u are each 0 or 1.
