Abstract: PURPOSE: A method for preparing a clay-dispersed olefin-based polymer nanocomposite and a polyolefin resin by using the nanocomposite are provided, to improve the tensile strength and the heat transformation temperature without deterioration of the transparency. CONSTITUTION: The method comprises the steps of dipping a catalyst for polymerization of olefin into clay, dipping a co-catalyst into clay, and polymerizing the olefin, wherein the clay is an organic treated clay having a functional group capable of a catalyst being supported to, the catalyst for polymerization of olefin is a Ziegler-Natta catalyst where chlorine or oxychloride is bonded with titanium or vanadium, and the co-catalyst is an organoaluminum. Preferably the clay is selected from the group consisting of montmorillonite, hectorite, saponite, sauconite, vermiculite, magadiite and kenyaite; the catalyst for polymerization of olefin is an organometal complex bonded with a metal selected from Zr, Ti, Ni and Pd; and the organoaluminum used as a co-catalyst is selected from (C2H5)3Al, (C2H5)2AlCl, (C2H5)AlCl2, (t-C4H9)3Al and (iso-C4H9)3Al.
