  Doubly [SiMe2]-bridged Cs- and C2v-symmetric zirconocene catalysts for propylene polymerization. Synthesis and polymerization characteristics

  摘要：

  The C-s- and C-2v-symmetric doubly dimethylsilylene-bridged zirconocene complexes (Me2Si)(2){eta(5)-C5H2-4-CHMe2}{eta(5)-C5H-3,5-(SiMe3)(2)}ZrCl2, 6a, and (Me2Si)(2){eta(5)-C5H-3,5-(CHMe2)(2)}(2)ZrCl2, 6b, have been synthesized by reaction of corresponding dilithio ligand salts with ZrCl4 in CH2Cl2. When activated with methyl aluminoxane, C-s-symmetric zirconocene 6a catalyzes the polymerization of propylene (liquid propylene, 0 degrees C) to yield a syndiotactic polymer of Mw = 1,000,000 and rrrr% = 75.4. By contrast, C-2v-symmetric zirconocene 6b displays a low activity and affords an atactic polymer. (C) 1998 Elsevier Science B.V.
