Abstract
Abstract Novel polymeric compositions and processes for employing the same as autoxidation catalysts in the oxidation of olefins and secondary and tertiary alkylaromatic compounds are provided herein. These novel compositions comprise organometallic compounds which incorporate in the backbone or on side groups in the polymer polar units capable of binding suitable metal ions which together form the oxidation catalyst.
