Abstract
Ortho ester-substituted chlorotriazines are prepared by the reaction of a dichlorotriazine with a reactive compound containing an ortho ester group, preferably a 4-(2-methoxy-2-methyl-1,3-dioxolan-4-yl)methyl group. They are useful as capping agents for polyphenylene ethers. The capped polyphenylene ethers form copolymer-containing compositions with polyesters, polyamides and other polymers containing carboxylic acid or amine groups.
