Title:
2種金属からなるオレフイン重合触媒
Document Type and Number:
Japanese Patent JP4242150
Kind Code:
B2
Abstract:
A bimetallic olefin polymerization catalyst is described. The catalyst comprises an organometallic compound, and optionally, an activator. The organometallic compound comprises a Group 3-5 transition or lanthanide metal, M1, a Group 6-10 transition metal, M2, and a multidentate ligand characterized by a cyclopentadienyl group that is covalently linked to two Group 15 atoms, wherein the cyclopentadienyl group is pi-bonded to M1 and the two Group 15 atoms are coordinated to M2. The bimetallic catalyst is useful for producing copolymers from ethylene without using a co-monomer by oligomerizing ethylene and simultaneously polymerizing ethylene and the co-formed oligomer.
