Abstract
Provided is a process for polymerization and copolymerization of ethylene, specifically comprising carrying out polymerization or copolymerization ethylene in the presence of (a) a solid complex titanium catalyst which is produced by the process comprising: (i) preparing a magnesium compound solution by contacting a halogenated magnesium compound and an alcohol for allowing a reaction; (ii) reacting the resulted magnesium compound solution with an ester compound having at least one hydroxyl group and a silicon compound having at least one alkoxy group; (iii) reacting the resulted solution with a mixture of a titanium compound and a silicon compound to obtain a solid titanium catalyst component; (iv) washing the resulted solid titanium catalyst component with a halogenated saturated hydrocarbon compound; and (v) further reacting the washed solid titanium catalyst component with a titanium compound to obtain a solid complex titanium catalyst, and (b) an organometallic compound from Group II or III of Periodic table of elements. According to the present invention, it is possible to provide a process for polymerization or copolymerization of ethylene in which the catalyst activity is improved and a polymer of high bulk density is provided, with the use of a catalyst prepared by a simple process.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
