| titleOfInvention | Prepolymerization catalyst for use in gas phase polymerization of olefins and process for producing the same |
| abstract | The present invention comprises (A) a solid catalyst component comprising magnesium, halogen, titanium and electron donors, having a weight average particle diameter of 15 to 45 μm, (B) one or more organoaluminum compounds and (C) ethylene and / or one or more A prepolymerization catalyst for gas phase polymerization of an olefin or an olefin compound comprising a prepolymer of α-olefin, wherein the molar ratio of aluminum to titanium in the prepolymerization catalyst (Al / Ti ratio) is 3 to 11 (mol / mol) The weight ratio (prepolymerization catalyst / solid catalyst component ratio) of the prepolymerization catalyst to the solid catalyst component is 2 to 35 (g / g), and the content of volatile matter (VM) in the prepolymerization catalyst is 2.0 wt% or less. , A prepolymerization catalyst for gas phase polymerization of an olefin or an olefin compound, characterized in that the intrinsic viscosity [?] Measured in tetralin at 135 ° C. is 2.0 dl / g or less, and a method for producing the same. According to the present invention, it exhibits high activity in gas phase polymerization, does not significantly form aggregates and coarse particles during prepolymerization, has a high bulk density and excellent fluidity, and prepolymerization catalyst and powder from a fluidized bed during gas phase polymerization. A prepolymerization catalyst may be provided for use in the gas phase polymerization of olefins which does not significantly release the product, is almost completely free of polymer aggregates and produces olefin polymers with a low content of cold xylene-soluble fractions. |
