In this study, 1-octene/ethylene copolymerization was performed by preparing a Ziegler-Natta catalyst supported on MgCl2 through a chemical method. To prepare a heterogeneous catalyst, a magnesium source was reacted with alcohol, and then aluminum compound and TiCl4 were sequentially added to this solution. Three catalysts having Mg/Al molar ratios of 0.5, 1.0, and 1.5, respectively, were synthesized, and the molar ratios of 1-octene/ethylene were set to 0, 0.5, and 1.0 during copolymerization. PE polymerization was carried out through a high-pressure reactor equipped with a stirrer, and the physical properties of the resulting polymer were analyzed using FT-IR, XPS, GPC, and SEM instruments. |
