Zusammenfassung:	T 1154 PROCESS FOR MODIFICATION OF POLYPHENYLENE ETHER OR RELATED POLYMERS WITH A CYCLIC ACID ANHYDRIDE AND THE USE THEREOF IN MODIFIED, HIGH TEMPERATURE RIGID POLYMER OF VINYL SUBSTITUTED AROMATICS Process for the manufacture of modified polyphenylene ether or structurally related polymers, comprising the reaction of polyphenylene ether or structurally related polymer with a cyclic acid anhydride, in the presence of a non nucleophilic base, and in an inert polar organic solvent and preferably in a vinyl substituted aromatic monomer as solvent; modified polyphenylene ethers so obtained and use of them for the manufacture of modified high temperature rigid poly(vinyl substituted aromatic) polymer compositions.
