| titleOfInvention | FLUORINE-CONTAINING α-DIIMINE NICKEL COMPLEXES FOR PREPARING POLYOLEFIN ELASTOMER AND INTERMEDIATES, AND PREPARATION METHOD AND USE |
| abstract | Disclosed are a class of fluorine-containing α-diimine nickel complexes for preparing a polyolefin elastomer and intermediates thereof. The class of complexes have a single catalytic active center, the molecular weight of a polymer can be regulated and controlled by changing a ligand structure and the polymerization conditions, and the complexes have advantages including a high catalytic activity, a low cost and a stable performance. Also provided are methods for preparing an asymmetric α-diimine nickel complex containing a difluoro group and an intermediate thereof. The two preparation methods have advantages such as mild reaction conditions, short periods, and simple operation conditions. Also provided are the uses of a metal nickel complex and a catalyst system thereof for catalyzing ethylene polymerization, wherein the metal nickel complex and the catalyst system thereof exhibit a very good catalytic activity, and a polyethylene elastomer material with a narrow molecular weight distribution is thus obtained. The obtained polyethylene elastomer material has a high degree of branching, and also has a good tensile strength, elongation at break and elastic resilience. The obtained polyethylene elastomer material is a thermoplastic elastomer material and has excellent industrial application potential. |
