Catalyst component for alpha-olefin polymerization and use thereof. |
摘要 |
<p>A supported titanium catalyst component for use in propylene polymerization is prepared by copulverizing a mixture of magnesium dichloride and titanium teterachlcor- ide ethylbenzoate 1: 1 adduct, and then treating the resulting titanium containing solid with n-heptane solution of hexachloroethane in slurry state.</p><p>The titanium catalyst component thus treated has larger surface area and pore volume than untreated one and gives a characteristic X-ray diffraction pattern. The supported titanium catalyst with organo aluminum and ethylbenzoate as cocatalyst gives high catalyst efficiency and heptane insolu- bles in polymerization of propylene.</p> |
