Specifically, this invention pertains to a transition metal catalyst which has stability under high temperature solution polymerization at 120 ~ 250 °C, in which a cyclopentadiene derivative and an electron donating substituent, both of which are bonded to a Group IV transition metal acting as a central metal, are crosslinked through a silyl derivative substituted with a cyclohexyl, to a catalyst system including such a transition metal catalyst and an aluminoxane cocatalyst or a boron compound cocatalyst, and to a method of producing an ethylene homopolymer or an ethylene copolymer with α-olefin, having high molecular weight, using the catalyst system under conditions of high-temperature solution polymerization. The catalyst according to this invention has excellent thermal stability and compatibility with a paraffin hydrocarbon solvent and thus is effective in the production of an ethylene homopolymer or an ethylene copolymer with α-olefm having various properties in commercial polymerization processes.

摘要： Disclosed are an ethylene polymerization process, a catalyst for use in the process, a production method employing the catalyst, and a product produced thereby. More specifically, disclosed is a process of producing an ethylene copolymer from ethylene and an alpha-olefin comonomer, in which the produced ethylene copolymer has a multimodal molecular weight distribution and excellent processability and physical properties, and thus can increase the value and productivity of products, including pipes and films. Particularly, the produced ethylene copolymer has a trimodal or higher molecular weight distribution or density distribution, and thus, when it is a linear low-density copolymer, it has an excellent effect of improving the impact strength of films, and when it is a medium-density ethylene copolymer, it can be produced into pipes, which have slow crack growth rate and can be used even at high temperature.

摘要： The present invention relates to a method of preparing an ethylene polymerization catalyst, which comprises reacting a solid reaction product of magnesium halide (such as magnesium chloride), alcohol, an organic magnesium compound, and a halogen compound with a transition metal compound and an electron donor. When ethylene and a-olefin are co-polymerized by slurry polymerization in the presence of the above catalyst, the amount of wax component extracted by the polymerization solvent is very low, and the polymer particles do not agglomerate. The catalyst is prepared in the form of so uniform particles that the resultant polymer has uniform particle morphology, thus increasing bulk density.
