Abstract

Dinuclear complex catalysts often show different catalytic bahavior compared to the corresponding mononulcear complex catalysts. Most of the previously reported dinuclear catalysts contain two mononuclear complexes connected by a flexible tether. Herein we report double-decker type dinuclear complex catalysts having two metal centers located on cyclic ligands in close proximity. They show a higher catalytic activity than the mononuclear analogue, and gave polymers with higher molecular weight. The dinuclear catalysts also promote copolymerization of olefins with various comonomers and gave copolymers with unique structures. It was also revealed that the dinuclear catalysts are stable at elevated temperature.
