Process for producing olefin polymer. |
摘要 |
<p>A solid catalyst component containing a trivalent titanium compound, obtained by reducing a titanium compound represented by the general formula Ti(OR<1>)nX4-n (wherein R<1> is a hydrocarbon group of 1 to 20 carbon atoms, X is a halogen atom, and n is a number satisfying 0 < n </= 4) with an organomagnesium compound in the presence of an alcohol compound and/or a phenol compound to obtain a solid product and then treating the solid product with a mixture of an ether compound and titanium tetrachloride; a catalyst system comprising: (A) said solid catalyst component, and (B) an organoaluminum compound; and a process for producing an olefin polymer, which comprises homopolymerizing an olefin or copolymerizing olefins using said catalyst system.</p> |
