Abstract
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.
