PROCESS FOR PRODUCTION OF ETHYLENE-BASED POLYMERS

摘要

A process for producing ethylene-based polymers by polymerizing ethylene or ethylene and other alpha -olefins by the use of a catalyst consisting essentially of (A) a transition metal compound component and (B) an organometallic compound component, said component (A) being a reaction product of (i) a specified chromium compound with (ii) a specified metal compound, and said component (B) being a halogen-containing alkylaluminium compound. According to the present invention, ethylene-based polymers can be efficiently produced.
