| 摘 要： | 综述了主要与Ti,Zr,Hf等过渡金属络合的FI催化剂配体(即苯氧基亚胺配体)的研究进展。对苯氧基亚胺配体进行修饰主要是在其亚胺基、苯氧基邻位以及对位引入取代基团(分别以R1,R2,R3表示)。其中,R1基团的体积主要影响聚合物的相对分子质量,而氟代的R1基团不仅能使Ti-FI催化剂的活性显著提高,还能获得优异的活性聚合性能。R2基团的体积强烈地影响Zr-FI催化剂的活性,其位阻越大Zr-FI催化剂的活性越高。在苯氧基的对位引入R3供电子基团可大幅提高FI催化剂的热稳定性。双核FI催化剂具有优异的乙烯/α-烯烃共聚性能。

| Abstract: | This commentary reviews the development of the ligands of FI 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 R1 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... |
