Abstract
The present invention relates to a catalyst for homo-polymerization or co-polymerization of ethylene, or more particularly to a solid complex titanium catalyst for homo-polymerization or co-polymerization of ethylene. The catalyst may be produced by preparing a magnesium solution by contact-rcacting a magnesium halide compound with alcohol. Reacting the solution with an ester compoound and a silicon compound. Then reacting the solution with a mixture of a titanium compound and a silicon compound.
Claims23
A method for producing a solid titanium catalyst for homo-polymerization and co-polymerization of ethylene, comprising:
- preparing a magnesium compound solution by contacting a magnesium halide compound with an alcohol;
- preparing a second solution by reacting the magnesium compound solution with an ester compound comprising at least one hydroxy group and a first silicon compound, wherein the first silicon compound comprises a silicon compound having an alkoxy group;
- and
- reacting the second solution with a mixture of a titanium compound and a second silicon compound to produce the solid titanium catalyst, the second silicon compound comprising a silicon halide.
