FI催化剂配体的研究进展
Progress in Research of the Ligands of FI Catalyst
摘要
Abstract
This commentary reviews the development of the ligands of Fl catalyst (namely phenoxy-imine ligand), which mainly complex with transition metal Ti, Zr, Hf, et al. In order to modify phenoxy-imine ligands, various desired substituents are introduced to imine, ortho- and para-position of phenoxy (which represent by R1, R2 and R3 respectively). The bulkiness of R, group mainly influences relative molecular mass of polymer. Fluorinated R1 group can not only enhance the activity of Ti-FI catalysts significantly, but also show excellent living polymerization feature. The bulkiness of R2 group has a dramatic effect on Zr-FI catalyst's activity, the more steric hindrance it is, the higher activity can be obtained. Introducing electron-donating group to the para-position of phenoxy group would greatly enhance the thermal stability of FI catalysts. Binuclear FI catalysts exhibit good ability for ethylene/a-olefin copolymerization.关键词
