| titleOfInvention | Phenylethyl-contained N, N coordinated nickel ethylene polymerization catalyst and application as well as application |
| abstract | The invention discloses a phenylethyl-contained N, N coordinated nickel ethylene polymerization catalyst which is obtained by introducing a strong electron-donating group and large-volume group phenylethyl into an ortho-position and a para-position of an imine nitrogen atom aromatic ring. Simultaneously, the space effect of large-volume ligands greatly reduces the rate of an activity chain transferring to a monomer so that a macromolecular polymer is obtained. Because the phenylethyl has strong electron-donating performances, the electron cloud density at the metal center of a catalyst is increased, and the catalyst stability is improved; and along with the progress of the reaction, the number of activity centers is reduced, so that the catalyst has a relatively high ethyl polymerization activity. With the existence of a promoter of diethylaluminium chloride, the activity of the diethylaluminium chloride in the promoting of the ethyl polymerization can reach 106gPE/(mol.Ni.h.bar), and the obtained polyethylene has a relatively high branching coefficient which can be up to 142 branch/1000C. Therefore, the polymerization catalyst has a very good application prospect in the polyethylene industry. |
