Problems solved by technology

[0004] Although polyolefin materials have such a large amount of use, there are still some problems to be solved, such as because polyolefin is a non-polar material, its adhesion, wettability and miscibility are relatively poor (J.-Y.Dong, Y. Hu, Coord. Chem. Rev. 2006, 250, 47.)
Late transition metals can catalyze the copolymerization of olefins and polar monomers, making it a research hotspot in recent years. However, in order to achieve better copolymerization effects, there are still some problems to be solved. The three main problems are: 1. Polar functional group to metal; 2, forming a stable metal-alkyl chelating ring to deactivate the metal; 3, rapid β-X elimination
(B.S.Williams, M.D.Leatherman, P.S.White, M.Brookhart, J.Am.Chem.Soc.2005, 127, 5132.) And due to the fast chain walking characteristics of the Brookhart type catalyst, even if long-chain polar monomers are used (Introduction of methylene between the double bond and the polar functional group) can not achieve the above-mentioned polar monomer copolymerization
The characteristic of chain walking also makes the polymer product catalyzed by this catalyst amorphous, which further limits the application of this type of polymer.

Abstract

The invention provides a compound as shown in formula (I) and a complex catalyst. The compound is based on the ligand effect of second layer space among molecules, and ensures that the second layer coordination space strategy is applied to olefin body polymerization and the copolymerization of olefin and polar monomers, so as to obtain a good technical effect. The complex catalyst belongs to palladium, nickel and iron catalysts containing alpha-diimine ligands with second layer coordination space effect, in the system, beta-H and beta-X elimination is restrained through the second layer coordination space effect, but normal coordination of ethylene is not prevented, therefore, the occurrence of chain walking is restrained, the polyethylene branching coefficient is reduced, and the copolymerization of ethylene and more polar monomers is realized.
