  • Polymerization of MMA by oscillating zirconocene catalysts, diastereomeric zirconocene mixtures, and diastereospecific metallocene pairs
    作者:Yalan Ning、Megan J. Cooney、Eugene Y.-X. Chen
    DOI:10.1016/j.jorganchem.2005.01.070
    日期:2005.12
    Characteristics of methyl methacrylate (MMA) polymerization using oscillating zirconocene catalysts, (2-Ph-Ind)(2)ZrX2 (X = Cl, 1; X = Me, 2), mixtures of rac- and meso-zirconocene diastereomers, (SBI)ZrMe2 [3, SBI = Me2Si(Ind)(2)] and (EBI)ZrMe2 [4, EBI = C2H4(Ind)(2)], as well as diastereospecific metallocene pairs, rac-4/Cp2ZrMe2 (5) and rac-4/CGCTiMe(2) [6, CGC = MeSi(Me4C5)(t-BuN)], are reported. M MA polymerization using the chloride catalyst precursor 1 activated with a large excess of the modified methyl aluminoxane is Sluggish, uncontrolled, and produces atactic PMMA. On the other hand, the polymerization by a 2/1 ratio of 2/ B(C6F5)(3) or 2/Ph3CB(C6F5)(4) is controlled and produces syndiotactic PMMA. Mixtures of diastereorneric ansa-zirconocenes 3 or 4 containing various rac/meso ratios, when activated with B(C6F5)(3), yield bimodal PMMA; this behavior is attributed to the meso-diastereomer that, in its pure form, affords bimodal, syndio-rich atactic PMMA. For MMA polymerization using diastereospecific metallocene pairs, rac-4/5 and rac-4/6, the isospecific catalyst site dominates the polymerization events under the conditions employed in this study, and the aspecific and syndiospecific sites are largely nonproductive, thereby forming only highly isotactic PMMA.
