    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.

    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： Provided is a method for improving thermal stability of polypropylene carbonate and, more particularly, a method of end capping a molecular chain of polypropylene carbonate using a urethane group by adding isocyanates or diisocyanates to a polypropylene carbonate resin, which may optionally be a mixture containing tertiary polyol, so as to delay thermal degradation of the polypropylene carbonate at a high temperature, thereby securing desired thermal stability. Especially, the method capable of being easily applied to reactive extrusion after preparing the polypropylene carbonate has been proposed, thus simplifying production processes and ensuring economical advantages. Moreover, the above method does not deteriorate transparency and specific smoke density characteristics at combustion, which are advantages of the polypropylene carbonate.
