VANADIUM COMPLEX, OLEFIN POLYMERIZATION CATALYST AND METHOD FOR PRODUCING OLEFIN POLYMER

摘要

PROBLEM TO BE SOLVED: To provide a new vanadium complex usable as a component of an olefin polymerization catalyst.;SOLUTION: The invention provides a vanadium complex expressed by formula (1) (in the formula, A is a group 14 element of the periodic table of elements; Cp is a group having a cyclopentadienyl-type anion skeleton; V is a 4-valent vanadium atom; R¹, R², R³, R⁴, R⁵ and R⁶ are each independently a hydrogen atom, a halogen atom, a 1-20C alkyl group or the like; X¹ and X² are each independently a hydrogen atom, a halogen atom, a 1-20C alkyl group or the like; Y¹ is a neutral ligand; and k is an integer of ≥0), a method for producing the complex, an olefin polymerization catalyst component composed of the vanadium complex expressed by formula (1), and a method for producing an olefin polymer.;COPYRIGHT: (C)2008,JPO&INPIT
