Preparation method of pyridylamino binuclear metal titanium zirconium hafnium catalyst and application of catalyst in olefin polymerization

According to the invention, rigid anthracene is introduced as a framework of bridged binuclear metal, a pyridylamino binuclear metal titanium-zirconium-hafnium catalyst is constructed, and the molecular weight of the obtained polymer can be effectively improved through the synergistic effect between the binuclear metal and the steric hindrance and electronic effect on the catalyst structure; the polyolefin elastomer (POE), the isotatic polypropylene (iPP) and the propenyl elastomer (PBE) are efficiently synthesized. The pyridylamino binuclear metal titanium-zirconium-hafnium catalyst has the advantages that synthesis is simple, raw materials are easy to obtain, and the product yield is high. In copolymerization of ethylene and alpha-olefin, the catalyst shows excellent activity (5.75 * 10 < 7 > g (POE). Mol <-1 > (M). H <-1 >) and alpha-olefin selectivity (the insertion rate reaches 16.2 mol%), and the polyolefin elastomer POE with excellent performance is prepared. In propylene polymerization, the regularity of the polypropylene chain segment can be effectively regulated and controlled by adjusting the steric hindrance and the electronic effect of the catalyst, and the regularity gt is prepared with high activity (3.84 * 10 < 7 > g (PP). Mol <-1 > (M). H <-1 >); and the polypropylene material with high stereoregularity is prepared from 80 mmmm% of polypropylene with high stereoregularity. In copolymerization of ethylene and propylene, an elastomer material which takes propylene as a main material, can regulate and control the ethylene content to be 5-50 wt% and has unique characteristics of a propylene-ethylene semi-crystalline copolymer is prepared. In addition, the pyridylamino binuclear metal titanium-zirconium-hafnium catalyst also shows excellent high-temperature resistance (higher than 160 DEG C), is suitable for high-temperature solution polymerization, and can be used for preparing high-performance polyolefin elastomers. Therefore, the invention has original innovation, and provides a new direction for the development of the field of polyolefin materials.
