Abstract

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.
