Abstract
A process for depolymerizing polymers by selective, partial oxidation at supercritical or near supercritical conditions for water and wherein supercritical water or water near supercritical conditions is used as a solvent and reforming agent, is used to produce relatively high yields of the monomers originally used to produce the polymers. The invention provides an environmentally friendly process for recycling polymeric waste materials to generate valuable polymer feedstock in a closed oxidation process which is free of hazardous stack emissions. The polymers which can be recycled in accordance with the process can include typical amounts of conventional additive and other impurities without significantly affecting the overall conversion.
