遷移金属化合物及びオレフィン系重合体の製造方法
Document Type and Number:
Japanese Patent JP6921563
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a transition metal compound catalyst that makes it possible to synthesize an olefin polymer that is soft and has improved catalytic activity and reduced stereoregularity, and a method for producing an olefin polymer.SOLUTION: The present invention provides a compound represented by formula (IV) (X is a σ-binding or π-binding ligand; Y is a Lewis base; Y may be crosslinked to other Y and X; q is an integer of 1-5 and [(valence of M)-2]; r is an integer of 0-3; Rand Rindependently represent H or halogen, alkyl or the like; R-Rare alkyl groups. M is metal elements of groups 3-10 or lanthanoid series in the periodic table; A-Aindependently represent a crosslinking group composed of group 14 (C, Si, Ge, Sn)).SELECTED DRAWING: None
