Abstract
The present invention relates to an amine bridged metallocene catalyst, a method for producing the same, and a method for producing an ethylene-alpha olefin copolymer, which comprises polymerizing ethylene and alpha olefin in the presence of an olefin polymerization catalyst composition including a metallocene catalyst. The amine bridged metallocene catalyst may be produced by reacting one or more of substituted or unsubstituted cyclopentadiene and substituted or unsubstituted fluorene with amine to bridge them with nitrogen, and reacting them with a transition metal to coordinate them.
