Abstract

A process for recovering a reusable vinyl chloride polymer composition from the plastic waste resulting from the manufacture of articles of a vinyl chloride polymer composition, and a plasticizer composition, which process is characterized in that it comprises the steps of (a) contacting said plastic waste with a solvent of said vinyl chloride polymer, (b) contacting the resulting liquid phase with a non-solvent of said vinyl chloride polymer composition said non-solvent effective to dissolve said plasticizer and (c) separate the resulting solid phase containing said vinyl chloride polymer to leave a liquid phase containing said plasticizer composition.
