NEW TRANSITION METAL COMPOUND, OLEFIN POLYMERIZATION CATALYST COMPONENT COMPRISING THE SAME, OLEFIN POLYMERIZATION CATALYST CONTAINING THE SAME, AND METHOD OF POLYMERIZATION OF OLEIN

Japanese Patent JP3423378

B2

PURPOSE: To obtain an olefin polymerization catalyst which makes it possible to produce a polyolefin having high melting point, high molecular weight, and a narrow molecular weight distribution and composition distribution with high activity by using a specified transition metal compound as the constituent.
CONSTITUTION: A transition metal compound represented by the formula (a new substance). This compound can be used as an olefin polymerization catalyst component. For example, a catalyst consisting of a transition metal compound (A) of the formula and at least one compound (B) selected from an organoaluminum oxy compound and a compound that reacts with the compound A to form an ion pair can be used as an olefin polymerization catalyst. In the formula, M is a group IVa, Va or VIa transition metal; R is a 1-20C hydrocarbon group; R2 is a 1-16C aryl group substituted by a 1-20C halogenated hydrocarbon group; X1 and X2 are each H, halogen or a 1-20C hydrocarbon group; and Y is a 1-20C hydrocarbon group, a 1-20C divalent halogenated hydrocarbon group, etc.
