Abstract: Methods for preparing end-functionalized polyolefin. The methods include polymerizing one or more olefin monomers in the presence of an aluminum chain transfer agent to produce a polymeryl aluminum species; treating the polymeryl aluminum species with sulfur oxide compound at a reactor temperature to form a polymeryl sulfinate; and oxidizing the polymeryl sulfinate; wherein the end-functionalized polyolefin comprises a polymer backbone having at least 30 carbon atoms; and the end-functionalized polyolefin comprises a sulfur containing group.
