  Ortho ester-capped polyphenylene ethers are prepared by the reaction of a polyphenylene ether with a reactive compound containing an ortho ester group, preferably a 4-(2-methoxy-2-methyl-1,3-dioxolane-4-yl)methyl group. Chlorotriazines containing the ortho ester substituent are particularly preferred as capping agents. The capped polyphenylene ethers form copolymer-containing compositions with polyesters and other polymers containing carboxylic acid groups.

  In various embodiments the present invention comprises 2,4,6-trisubstituted-1,3,5-triazine capping agents comprising one, two, or three leaving groups as substituents with any remaining substituents being essentially inert to reaction with a nucleophilic group on a polymer or monomer, or reactive with a nucleophilic group on a polymer or monomer at a slower rate than any leaving group. The invention also comprises polymers or monomers with nucleophilic groups capped with a triazine moiety. Still other embodiments of the invention comprise processes for capping nucleophilic groups in a polymer or monomer which comprises combining and reacting the polymer or monomer with a triazine-comprising capping agent.
