Description

Fluorine-containing phenylamidine metallocene catalyst, preparation method and application thereof

Technical Field

The invention belongs to the field of chemical synthesis, and relates to a fluorine-containing phenylamidine metallocene catalyst, and a preparation method and application thereof. Is suitable for catalyzing and synthesizing high molecular weight atactic polyolefin.

Background

There are many different catalysts and processes in the field of olefin polymerization. Polyolefins having a higher molecular weight and a narrower molecular weight distribution are often the target products in mass production processes because such polyolefins have better mechanical strength. Although conventional Ziegler-Natta catalysts can produce polyolefins having high molecular weights, they have a broad molecular weight distribution.

Metallocene catalysts are olefin polymerization catalysts consisting of metallocenes and organic ligands. Compared with the traditional olefin polymerization catalyst, the metallocene catalyst has better polymerization behavior, and can endow the polyolefin material with unique structure and performance, such as good impact strength and toughness, good melting property and the like. Many polar monomers, and monomers traditionally thought to be non-polymerizable, can be used to synthesize new polymeric materials. Metallocene catalysts were first put into commercial use in the united states in 1991 at 6 months. With the improvement of the requirements of production and life on materials, the research on the metallocene catalyst has wide application and market prospect.

At present, metallocene catalyst researchers have come together with the belief that ligands are key to the design of new polymerization catalysts. The steric effect and electronic effect of the ligand and the configuration of the catalyst caused by the steric effect and electronic effect have important influence on the catalytic performance. Therefore, searching for new metallocene catalyst ligands and optimizing the ligand synthesis process can not only reduce the production and research costs, but also simply and rapidly adjust the space and electronic structure of the metallocene catalyst, thereby controlling the polymerization process.

WO2008148499A1, WO2008151776A1 and WO2009063084A2 report dimeric fluoroanilide metallocene catalysts and their use in the catalytic synthesis of very large molecular weight polypropylene, which have surprising catalytic activity compared with other catalysts.
