Supported catalyst composition for polymerization of olefins; method for preparing the same and process for polymerization using the same

摘要

The present invention relates to a supported catalyst composition for polymerization of olefins comprising: (i) a titanium compound, a magnesium compound and at least one electron donor compound; (ii) a chlorine and/or oxygen containing polymer support; and (iii) a cocatalyst comprising at least one aluminium compound; a method for preparing a supported catalyst composition according to the present invention; and a process for homopolymerization of ethylene or copolymerization of ethylene with alpha-olefins and/or diolefins by contacting ethylene or ethylene and alpha-olefins and/or diolefins with a catalyst composition according to the present invention.
