    摘要:
    在甲苯中,锆茂催化体系Ph2CCpFluZrCl2-聚甲基铝氧烷(MAO)和rac-Me2Si(2-Me,4-PhInd)2ZrCl2-MAO(Flu是芴基,Ind是茚基)的电子吸收光谱随反应物AlMAO/Zr的摩尔比从0到3000的变化而变化。使用统计方法分析光谱数据,确定每个体系中的反应产物数量。提出了一个包含三个平衡且适用于两个体系的反应模型。通过实验光谱的参数自建模,确定了有效平衡常数和单个反应产物的吸收光谱。

    名称:
    Propylene polymerization of ansa-complexes (RXPh)2C(Cp)(Flu)MCl2 (M=Zr or Hf) with halogen substituents on phenyl groups
    摘要:
    The catalytic properties of ((RPh)-Ph-X)(2)C(Cp)(Flu)MCl2 complexes (R-X = Cl, F or CF3; M = Zr or Hf) in propylene polymerization were studied. The results showed dependences of stereospecificity and polymerization activity on the substituent on phenyl group. When R-X is CF3, the activity is 1.38 times of that of the complex with no substituent at 1 atm propylene pressure and is extremely high at 3.0 MPa propylene pressure. The CF3 group increased the regioirregular insertion during polymerization to produce partially crystalline s-PP. When R-X is halogen, the obtained polymer has higher melting point than that obtained from the complex with no substituent. (C) 2004 Elsevier B.V. All rights reserved.

    Cs-Ligated ansa-zirconocene bis- and mono(ester enolate) complexes incorporating the diphenylmethylidene−(cyclopentadienyl)(9-fluorenyl) ligand, upon activation with appropriate activators, are highly active catalysts for the syndiospecific polymerization of MMA at ambient temperature, leading to the production of PMMA with high syndiotacticity (rrrr = 94%) and glass transition temperature (Tg = 139

    Highly stereoregular syndiotactic polypropylene is obtained with the catalyst systems Ph2C(Oct)(C5H4)ZrCl2/MAO (8/MAO) (Oct = octamethyloctahydrodibenzofluorenyl; MAO = methylaluminoxane) and Me2C(Oct)(C5H4)ZrCl2/MAO (12/MAO). The syndiotactic polypropylenes obtained are largely devoid of stereoerrors by 13C NMR analysis ([r] > 98%), and melting temperatures as high as 153 or 154 °C (from 8 and 12
