  • Silica gel-supported catalyst component for ethylene (co)polymerization, catalyst therefrom and use of the same
    Patent number: 6642325
    Abstract: The present invention relates to a silica gel-supported catalyst component suitable for ethylene (co)polymerization, a catalyst therefrom and use of the same. The catalyst component according to the present invention is obtained by supporting the reaction product of a titanium compound, a halide promoter, a magnesium compound and an electron donor on silica gel having a larger specific surface area. When the resultant catalyst is used for ethylene polymerization, especially gas phase fluidized bed polymerization, not only the activity is substantially enhanced, but also the hydrogen response and the copolymerizability of ethylene with other alpha-olefins are improved. The catalyst is especially suitable for the fluidized bed polymerization operated in a condensed state, with high quality LLDPE resins being obtained.
