Pay for it with plastic: Polyamides were directly converted to hydroxylcarboxylic esters or diols, chemicals that are more highly valued than simple monomeric materials, by treatment with supercritical MeOH in the presence of glycolic acid. Simple depolymerization along with efficient conversion of the amino group to hydroxyl group provides these compounds in high yields. This strategy may provide a new and economical solution for chemical recycling of waste plastics.
