USE OF TITANIUM AND ZIRCONIUM COMPOUNDS AS HOMOGENOUS CATALYST AND NOVEL TITANIUM AND ZIRCONIUM COMPOUNDS

Document Type and Number:

Japanese Patent JPH072924

Kind Code:

A

Abstract:

PURPOSE: To improve reaction efficiency by using a homogenous catalyst consisting of specific compds. containing Ti and Zr when an olefinic or an acetylenic unsaturated hydrocarbon is polymerized or oligomerized.

CONSTITUTION: A compd. represented by formula I (wherein M is Ti or Zr; X1 and X2 are each a halogen or a 1-20C aliphatic or aromatic hydrocarbon; O-O is groups represented by formulae II, III; R1 and R2 are each a steric hinderance alkyl, OR' or silyl; R' is a 1-20C aliphatic or aromatic hydrocarbon; R3 and R4 are each H, a 1-20C aliphatic or aromatic hydrocarbon, silyl or OR'; Y is methylene, ethylene or a divalent crosslinking group such as S, O or the like; (n) is 0 or 1) [e.g.; 2,2'-S(4-Me, 6-tBuC6H2O)2Ti(CH2Ph)2] is prepared. In the presence of a heterogenous catalyst comprising this compd., an olefinic or acetylenic unsaturated hydrocarbon (e.g.; ethene) is polymerized or oligomerized.
