ABSTRACT:
An improved free radical polymerization process employing as a polymerization initiator a bisquinone peroxide. Upon decomposition to initiate polymerization such bisquinone peroxides may also produce singlet oxygen capable of producing hydroperoxidized rubber if rubber is included in the polymerization mixture. The by-products formed from the decomposition of the bisquinone peroxide desirably comprise hindered phenolic compounds having antioxidant properties.
