POLYPHENYLENE ETHERS OF IMPROVED STABILITY ABSTRACT OF THE DISCLOSURE Polyphenylene ethers containing aminoalkyl- substituted end groups are sometimes undesirably reactive and unstable, especially at high temperatures. This problem is solved by reacting them, at temperatures within the range of about 200-300°C, with nitrogen compounds containing at least one N-H moiety, such as .epsilon.-caprolactam.
