| 摘要 |
Ethylene is polymerised, or copolymerised with another olefin monomer, using a catalyst system comprising an organic metal compound and a titanium-containing material which is obtained by reacting together an inert particulate material, an organic magnesium compound, a halogencontaining compound such as carbon tetrachloride, silicon tetrachloride, trichlorosilane, phosphorus trichloride or boron trichloride, and titanium tetrachloride. The process can be used to effect copolymerisation of ethylene with an alpha-olefin monomer such as butene-1 in a fluidised bed reactor. |
