| 摘要 |
The present invention provides an ethylene-alpha olefin-styrene copolymer including 50-80 wt% of an ethylene derived monomer, 10-40 wt% of an alpha olefin-based compound derived monomer, and 10-40 wt% of a styrene-based compound derived monomer based on a copolymer total weight. In addition, a weight average molecular weight of the copolymer is 50,000-200,000, density thereof is 0.875-0.900 g/cc, and a melting point (Tm) thereof is 40.0-70.0°C. According to the present invention, the ethylene-alpha olefin-styrene copolymer can be prepared using a catalyst composition including a transition metal compound, and a copolymer having higher density and a lower melting point, than a conventional copolymer, is provided. |
