Olefine polymerization process |
摘要 |
A catalyst component is a transition metal composition which is obtained by reacting together an inert particulate material, an organic magnesium compound, a halogen-containing compound such as carbon tetrachloride silicon tetrachloride or boron trichloride and a specified transition metal compound such as VOCl3, bis(n-butoxy) titanium dichloride or zirconium tetrabenzyl. The catalyst component obtained can be used, together with an organic metal compound, to give an olefin polymerization catalyst. The catalyst can be used to effect the polymerization of olefin monomers, for example, the copolymerization of ethylene with an alpha-olefin monomer such as butene-1 in a fluidized bed reactor.
