Abstract:
1. A polyolefin nanocomposite prepared by polymerizing an olefin monomer in a catalyst system, the catalyst system comprising (1) a supported catalyst consisting of a polymer, a silicate clay mineral, and a transition metal compound, and (2) an alkyl aluminoxane, wherein the polymer is one or more selected from the group consisting of acrylonitrile-based polymers, hydroxyl group-containing polymers, acryl-or acrylate-based polymers, maleic anhydride-containing or maleic anhydride-modified polymers, acetate-based polymers, polyether-based polymers, polyketone-based polymers, polyamide-based polymers, and polyurethane-based polymers.
