Catalyst and process for producing alpha-olefin polymers using the same |
| 摘要 |
A catalyst comprising: (A) a solid catalyst component containing a tri-valent titanium compound, which is obtained by reducing a titanium compound represented by the general formula Ti(OR1)nX4-n (wherein R1 is a hydrocarbon group having 1 to 20 carbon atoms, X is a halogen atom and n is a number satisfying 0<n</=4) with an organo magnesium compound in the presence of an organo silicon compound having Si-O bonds and then treating the resulting solid product with an ester compound and a mixture of an ether compound and titanium tetrachloride, (B) an organo aluminum compound, and (C) a silicon compound having Si-OR2 bonds (wherein R2 is a hydrocarbon group having 1 to 20 carbon atoms) and/or an organic carboxylic acid ester, and a process for producing alpha -olefin polymers using the same.
