- 6 - ABSTRACT OF THE DISCLOSURE The present invention relates to a process for reactively separating hydrolyzable polymers, such as PET, in mixtures of the polymer and certain non-hydrolyzable polymers, specifically polyole- fins by converting the hydrolyzable polymers to their corresponding water soluble components (e.g., PET to ethylene glycol and tereph- thalic acid) in the presence of liquid water at temperatures from about 200°C up to the critical temperature of water and autogenous pressure. The process has utility in recycling and waste material separation processes.
