Abstract

Highly heat-resistant polyaryl ether ketones are composed of PA1 (A) from 50 to 100 mol % of repeat units of the general formula I ##STR1## or a ring-substituted C.sub.1 -C.sub.8 -alkyl, C.sub.1 -C.sub.8 -alkoxy, aryl, chlorine or fluorine derivative thereof and PA1 (B) from 0 to 50 mol % of repeat units, different from I, of the general formulae II and/or III ##STR2## or a ring-substituted C.sub.1 -C.sub.8 -alkyl, C.sub.1 -C.sub.8 -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.
