Abstract:
A method of producing ethylene homo- or co-polymers, which comprises:a. producing a solid titanium catalyst by: i. producing a magnesium compound solution by contact-reacting a halogenated magnesium compound with alcohol; ii. reacting said magnesium compound solution with an ester compound having at least one hydroxy group, and a silicon compound having at least one alkoxy group; and iii. reacting the product of Step (ii) with a mixture of a first titanium compound and a silicon compound; and iv. reacting the product of Step(iii) with a second titanium compound b. producing ethylene homo- or copolymers in the presence of the solid titanium catalyst, an organometallic compound of Group 2, 12, or 13 of the Periodical Table, and an alkoxy silane compound.
