Abstract
An in situ controlled oxidation reaction of trialkylborane (BR ) in the presence of polyolefin and maleic anhydride produces mono-oxidized trialkylborane adducts, i.e., peroxyldialkylborane (R—O—O—BR ), that can undergo homolytic cleavage to form (R—O* *O—BR ) and activate the polyolefin chain by alkoxyl radical (R—O*) hydrogen-abstraction at ambient temperature. The formed polymeric radical (C*), associated with the oxidized borane moiety (*O—BR ), then reacts with maleic anhydride by addition reaction, without side reactions, to form functional polyolefins that contain incorporated maleic anhydride side groups.
