摘要：
Polyaryl ether ketones are prepared by electrophilic polycondensation using acyl halides as monomer components in the presence of a Lewis acid, by a process in which from 0.001 to 60% by weight of an inert filler or of a component which can be converted into an inert filler during working up are added to the reaction mixture before or during the polycondensation.
