Title:
ETHYLENE POLYMER PREPARATION METHOD
Document Type and Number:
WIPO Patent Application WO/2011/040556
Kind Code:
A1
Abstract:
Disclosed is a method for preparing an ethylene polymer with a low melting point in a more economical manner. In the ethylene polymer preparation method, ethylene is polymerized under the presence of an olefin polymerization catalyst that is obtained by bringing an olefin polymerization catalytic component that comprises a transition metal complex represented by the following general formula (1), a trimerization catalytic component that comprises a transition metal complex represented by the following general formula (2), and an activating co-catalytic component into contact.
