In this study, a polyethylene wax having a low molecular weight and a narrow molecular weight distribution was prepared by controlling various polymerization conditions such as temperature, hydrogen ratio, ethylene gas amount and polymerization pressure using various metallocene catalysts. We have evaluated hydrogen reactivity and studied on charactistics of polymerization effected by ligand structure of metallocene catalysts against Ziegler-Natta catalysts which are widely used for polymerization of polyethylene. Polyethylene waxes with very uniform physical properties polymerized through new methods can be effectively applied as coatings and Expanded Polystylene (EPS) cell sizers. The physical properties of the wax were confirmed by measuring Number average molecular weight(Mn), Weight-average molecular weight(MW) and Poly Dispersity Index(PDI) data of the polymerized polyethylene wax through Gel Permeation Chromatography(GPC). Keywords : Metallocene Catalyst, Polyethylene Wax, Polymerization Condition, Low Molecular Weight PE
