摘要:
Copolymer of ethylene and an alpha-olefin having (a) a density in the range 0.900-0.940 g/cm3, (b) a melt index MI2 (2.16 kg, 190° C.) in the range of 0.01-50 g/10 min, (c) a molecular weight distribution (Mw/Mn) in the range 3.5 to 4.5, and (d) a melt elastic modulus G′(G″=500 Pa) in the range 40 to 150 Pa. The copolymer has a melt index MI2 (2.16 kg, 190° C.) Dow Rheology Index (DRI) and melt elastic modulus G′(G″=500 Pa) satisfying the equations of [DRI/MI2]>0 and [DRI/MI2]
