| titleOfInvention | Method for preparing supported catalysts on modified support with functionalized catalyst precursor and its olefin polymerization |
| abstract | The present invention relates to a supported metallocene catalyst using a metallocene compound having a functional group which is easy to prepare a supported metallocene catalyst for olefin polymerization, and an olefin polymerization method using the supported catalyst.n n n The present invention is intended to describe substantially acetal, ketal, secondary or tertiary alkoxy alkyl, benzyloxy alkyl, substituted benzyloxy alkyl, aryloxy alkyl, dithioacetal, dithioketal, monothioacetal, monothioketal, thioether Or a silica prepared by removing a hydroxy group selectively from a hydroxy group and a siloxane group present on the surface of a silica by silane treatment of a silica dehydrated at a temperature of 500 ° C. or more by a metallocene compound having a functional group of an alkoxy silane on one part of a ligand. Provided is a supported metallocene catalyst supported by reaction with a carrier and an olefin polymerization method using the same.n n n In the supported metallocene catalyst of the present invention, a part of the ligand of the metallocene compound is attached to the silica surface by a strong chemical bond, so that almost no catalyst is liberated from the surface when activated so that the polyolefin can be prepared by slurry or gas phase polymerization. When there is little reactor fouling, and the particle shape and apparent density of the polymer to be produced is excellent, it can be used suitably for the conventional slurry or gas phase polymerization process. |
