Method for producing homo-and co-polymers of ethylene |
摘要 |
The present invention provides a method for producing homo- and co-polymers of ethylene, or more particularly a method for producing homo- and co-polymers of ethylene in the presence of (a) a solid titanium catalyst produced by preparing a magnesium solution by contact-reacting a halogenated magnesium compound with an alcohol; reacting thereto an ester compound having at least one hydroxyl group and a silicon compound having at least one alkoxy group; and adding a mixture of a titanium compound and a silicon compound; (b) organometallic compounds of Group II or III of the Periodic Table; and (c) an alkoxysilane compound and a haloalkane compound. The catalyst for homo- and co-polymerization of ethylene, produced according to the present invention, exhibits a high activity and the polymers produced by the method of the present invention using said catalyst have the advantages of exhibiting a high bulk density and a narrow molecular weight distribution.
