ABSTRACT:
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-dioxolan-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.
