摘要:
A constrained geometry single-site olefin polymerization catalyst is described. The catalyst comprises an activator and an organometallic compound that includes a Group 3 to 10 transition or lanthanide metal, M, and a multidentate ligand characterized by an indolyl group that is covalently linked to an amido group, wherein the indolyl group is &pgr;-bonded to M and the amido group is &sgr;-bonded to M. The indolyl-amido ligand is formed from readily available organic compounds and allows easy synthesis of a constrained geometry catalyst system.
