Abstract
PURPOSE: Titled film excellent in tensile strength, etc., comprising a copolymer obtained by copolymerizing, in a vapor phase, ethylene with an α-olefin in the presence of a catalyst prepared by combining an organic Al compound with a solid substance containing Mg and Ti and/or V.
CONSTITUTION: A catalyst is prepared by combining an organic Al compound, e.g., triethylaluminum, with a solid substance prepared by supporting a Ti compound and/or a vanadium compound on an Mg-containing inorganic carrier. Then, ethylene is copolymerized with 3W12C α-olefin in the presence of the catalyst and in the substantial absence of a solvent to obtain ethylene/α-olefin copolymer having a density of 0.89W0.945, a melt index of 0.1W5 and an n value, defined by the formula, of 1.3W3. Then, the stretched film of the purpose, useful for wrapping is prepared by molding the copolymer.
