Long chain-branched ethylene-alpha olefin copolymer |
| 摘要 |
The present invention relates to an ethylene-alpha olefin copolymer comprising long chain branches (LCB), while having a narrow molecular weight distribution. The ethylene-alpha olefin copolymer can be prepared by a continuous solution polymerization process using an activated catalyst composition containing a Group 4 transition metal compound having a monocyclopentadienyl ligand, to which a quinoline amino group is introduced. |

1. An ethylene-1-butene copolymer having
a) a molecular weight distribution (Mw/Mn) of 1.5 or above and less than 3.5 (1.5≦Mw/Mn<3.5); b) 3 to 5 long chain branches per 1000 carbons along the copolymer main chain; and c) a density of 0.863 to 0.865 g/cc.
