Supported metallocene catalyst system for olefin polymerization, method for making and using the same |
摘要 |
The present invention relates to a supported catalyst system for olefin polymerization which comprises at least one metallocene component and a support of an inorganic oxide of silica, aluminum or a polymer containing hydroxyl groups. The support is modified with an organogermane and/or organotin compound. The inventive catalyst system produces minimal reactor fouling, has excellent productivity and good hydrogen responsiveness. The present invention also relates to a process for preparing the catalyst system and to the slurry/suspension or gas-phase polymerization of olefins using the catalytic system, optionally with a small amount of aluminoxane cocatalyst.
