AI Technical Summary
Traditional mononuclear diimine nickel catalysts have limitations in terms of thermal stability, branching degree control, and catalyst life, making it difficult to meet the performance requirements of high-end polyolefin materials.
Polynuclear diimine ligand compounds and polynuclear diimine catalysts were designed to enhance thermal stability and reactivity through the synergistic effect of multiple metal centers, enabling precise control of polymer branching degree. Specific substituent groups were used to regulate catalyst performance.
It significantly improves the thermal stability and reactivity of the catalyst, enabling it to maintain high catalytic performance under high temperature conditions, achieve efficient synthesis of branched polyethylene, and meet the performance requirements of high-end polyolefin materials.
