1. The process of incorporating a modified polyphenylene ether into a poly (vinyl substituted aromatic) polymer by means of aqueous polymerization comprising the free radical polymerization of a vinyl substituted aromatic monomer in the presence of the modified polyphenylene ether, obtained by a previous reaction of a compound of the formula:
- ##STR7## wherein R1, R2, R3 and R4 are independently a hydrogen atom, a halogen atom or an alkyl group or an alkoxy group, both being optionally substituted by halogen, cyano, hydroxy or phenyl group, and having 12 or less carbon atoms, an aryloxy or arylalkoxy group, optionally substituted by halogen, hydroxy or cyano group and having 12 or less carbon atoms, a di(alkyl)amino group or a di(alkanoyl)amido group, wherein the alkyl groups have 12 or less carbon atoms, and wherein R1, R2, R3 and R4 may represent different or the same groups in one repeating unit, and n represents an integer having a value of at least 50, with a non-cyclic acid anhydride of the general formula;
##STR8## wherein R5 and R6 each independently may represent an alkyl, alkenyl, aryl or aralkyl group, containing from 1 to 12 carbon atoms and optionally being substituted by hydroxy, halogen, alkyl containing 1-4 carbon atoms, or a free or esterified carboxyl group, in the presence of a catalyst of the formula;
##STR9## wherein R9 and R10 both represent in general non-electron withdrawing groups and wherein the symbols R7 and R8 represent hydrogen, halogen or lower alkyl, while R7, R8, R9 and R10 may represent different or the same groups in one molecule, and in a vinyl substituted aromatic monomer as 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 non-cyclic acid anhydride, in the presence of a pyridine derivative substituted by an amine group as catalyst, and 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.
