摘要

PURPOSE: A mono-metallocene olefin polymerization catalyst containing a bis-Schiff base ligand, its preparation method and a polymerization or copolymerization method of -olefins using the catalyst are provided, to produce a polymerization products having a high molecular weight and a high insertion rate of comonomers by using the catalyst. CONSTITUTION: The mono-metallocene olefin polymerization catalyst is represented by the formula 1, wherein R1 is H, an alkyl group of C1-C12, an alkoxy group of C1-C12 or an aryl group of C6-C12; R2 and R2' are H or an alkyl group of C1-C4, respectively; R3 is H, an alkyl group of C1-C12, an alkoxy group of C1-C12 or an aryl group of C6-C12; and M is Ti, Zr or Hf. The preparation method comprises the steps of reacting the Schiff base ligand compound of the formula 2 with an alkyl alkali metal compound in an organic medium to obtain an alkali metal salt of a Schiff base ligand; and reacting the obtained metal salt with the cyclopentadienyl metal chloride of CpMCl3 (wherein Cp is a mono-substituted cyclopentadienyl group) in an organic medium.
