Title:

CATALYST FOR POLYOLEFIN POLYMERISATION AND A PRODUCTION METHOD FOR THE SAME

Document Type and Number:

WIPO Patent Application WO/2011/081404

Kind Code:

A2

Abstract:

The present invention relates to a production method for a catalyst for polyolefin polymerisation and to a catalyst for polyolefin polymerisation obtained by means of the same, and more particularly relates to a production method for a catalyst for polyolefin polymerisation, in which a magnesium halide precursor solution obtained by dissolving a magnesium halide in a first alcohol and a first hydrocarbon, and a dialkoxy magnesium carrier obtained by reacting a halogen compound and a second alcohol on metallic magnesium are reacted with titanium tetrachloride and an internal electron donor in the presence of a second hydrocarbon. By using the dialkoxy magnesium supported catalyst, the present invention can provide a catalyst for polyolefin polymerisation of a two-component magnesium compound supporting type which exhibits high activity.
