| titleOfInvention | A kind of fourth subgroup metal complex with rigid cyclic bridge structure and its application |
| abstract | The invention belongs to the technical field of olefin polymerization catalysts, and in particular relates to a metal complex of the fourth subgroup with a rigid cyclic bridge structure and its application. The fourth subgroup metal complex provided by the present invention has the structure of formula (A) or formula (B); X is halogen or alkyl; M is titanium, zirconium or hafnium. Based on the non-metallocene catalyst, the invention improves and upgrades the bridged structure in the middle of the catalyst molecule, and designs a brand-new metal complex with excellent catalytic performance and good high temperature tolerance; it is used as the main catalyst to catalyze olefins During the polymerization reaction, under the activation of a small amount of mixed cocatalyst, the copolymerization reaction of ethylene and α-olefin can be efficiently catalyzed to obtain a polyolefin with high molecular weight and high comonomer insertion rate. |
