Olefin polymerization catalyst. |
摘要 |
<p>An olefin polymerization catalyst which is obtained by contacting the following components (A) and (B): component (A): a product of contacting the following components (A1) and (A2): component (A1): polyolefin powder having specific values of pore diameter, pore volume, average pore diameter and average particle diameter, component (A2): a solid component for a Ziegler catalyst comprising titanium, magnesium and a halogen as the essential components; component (B): an organoaluminum compound. The supporting state of the catalyst is improved, and a contaminant-free polymer having a satisfactorily large particle diameter without the lowering of the activity or the stereoregularity of the catalyst is successfully obtained.</p> |
