1. Process for incorporating a modified polyphenylene ether into a poly(vinyl substituted aromatic) polymer, comprising polymerizing a vinyl substituted aromatic monomer in the presence of the modified polyphenylene ether obtained by a previous reaction of a polymer of the formula:
- ##STR4## wherein R1 and R4 each represent hydrogen, halogen, a phenyl group, alkenyl group, alkadienyl group, an aryloxy group, or wherein R1 and R4 each represent an alkyl group or an alkoxy group, each of the latter containing 12 or less carbon atoms and each optionally substituted by halogen, cyano, hydroxy, phenyl or amino, whereas alkyl or alkoxy groups attached to the terminal phenol nucleus of the chain optionally are substituted by an amino, dialkylamino or a di(alkanoyl) amide group, wherein the alkyl groups each contain 4 or less carbon atoms, wherein R2 and R3 each represent hydrogen, halogen, a phenyl group, alkenyl group, alkadienyl group, aryloxy group, or wherein R2 and R3 each represent a primary or secondary alkyl group or alkoxy group as defined for R1 and R4, optionally substituted by halogen, cyano, hydroxy, phenyl, and wherein R1, R2, R3 and R4 represent different or the same groups in one repeating unit, and n represents an integer having a value of at least 50, with a cyclic acid anhydride of the formula;
##STR5## wherein Y represents a bivalent radical of the formulae ##STR6## wherein m represents an integer in the range of from 2 to 8 and wherein R5 and R6 each independently represent an alkyl group of 1 to 4 carbon atoms, a phenyl group or an aralkyl group or wherein R5 and R6 together with the carbon atoms of the double carbon-carbon bond form a cycloalkenyl, cycloalkadienyl or aryl group, in the presence of a non nucleophilic base and in an inert polar organic solvent.

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.
