Abstract
Polyolefins having the same or different functional groups covalently bound to the polyolefin, such as polyolefins having hindered phenol groups bound thereto, can be prepared by from a maleic anhydride modified polyolefin, with or without a coupling agent, and a hindered phenol reagent under heat, e.g., by heating the components to at least about 170° C., such as by reactive extrusion. A polyolefin having hindered phenol groups can be added to the components as a stabilizer prior to or during reacting the components together under heat.
