|Title:||SILICA CARRIER AND PRODUCTION METHOD THEREFOR AND METALLOCENE CATALYST USING SAME|
The present invention relates to a silica carrier for a metallocene catalyst used in olefin polymerisation, to a production method therefor, and to a metallocene catalyst and an olefin polymer using same. More specifically, in the present invention, a specific halogenated metal compound is used in order to treat a silica carrier used when making an olefin supported catalyst, thereby diversifying reaction sites for an auxiliary catalyst when producing the metallocene catalyst and so making it possible to obtain a macromolecule and possible to greatly widen the molecular weight distribution of the olefin polymer as compared with hitherto even while supporting the same metallocene catalyst.
