    摘要: A polymer obtained by a solution polymerization process comprising within a range from 0.5 to 20 wt % of cyclic olefin derived units, within a range from 0 wt % to 15 wt % C4 to C12 α-olefin derived units, the remainder being ethylene derived units; and having a Mw/Mn of less than 2.5; a weight average molecular weight (Mw) within a range from 80,000 to 300,000 g/mole; and a g′ value of greater than 0.95. The polymer may be formed in a solution polymerization process comprising combining in a solution cyclic olefins, ethylene, hydrogen and optionally C4 to C12 α-olefins with a single-site catalyst to form the polymer, wherein the single-site catalyst is most preferably selected from unsymmetrical Group 4 bis-bridged cyclopentadienyl metallocenes.
