Document Type and Number:
Japanese Patent JP2002541152
Kind Code:
A
Abstract:
Neutral, multidentate azacyclic ligands and Group 3-10 transition metal complexes that contain them are disclosed. The ligands have the general formula: Ra-A-(L)b where R is hydrogen or hydrocarbyl, A is silicon, tin, germanium, or lead, each L is a pyrazolyl, triazolyl, or tetraazolyl group, a=0 to 2, b=2 to 4, and a+b=4. When used with common activators, the transition metal complexes provide excellent single-site catalysts for olefin polymerization.
