Oxidative Degradation of Nylon-6 and Nylon-6,6 with Nitrogen Dioxide in Supercritical Carbon Dioxide

Nylon-6 and nylon-6,6 were subjected to oxidative degradation with NO 2 in supercritical CO 2 . It was found that valuable short-chain α,ω-diacid mixture could be obtained in good yield under relatively mild conditions.
