Abstract
This study was conducted to analyze and characterize the properties of polyethylene wax polymerized and polymerized using various metallocene catalysts based on Indene and Cyclopentadien, which are different from Ziegler-Natta catalysts used in polyethylene polymerizatio n. The polymerization of polyethylene wax was carried out under various conditions by adjusting the polymerization temperature and the ratio of hydrogen gas used as a chain transfer agent and ethylene gas to metallocene catalysts containing ligands of different structures. The molecular weight and molecular weight distribution, The catalyst yields were compared and analyzed. As a result, the structure of a metallocene catalyst suitable for having a low molecular weight and a narrow molecular weight distribution was proposed and the ideal polyethylene wax could be polymerized.
