Abstract: | Syndiotactic polymerization of styrene in the presence of heterogenized hemititanocene catalysts CpTiCl3/Al2O3–SiO2/MAO (Cp = cyclopentadienyl; MAO = methylaluminoxane) showed that the yield and selectivity of this reaction depend on the support composition, i.e. on the Al2O3 content in the support. The most active catalysts contained Al2O3 in a quantity of 50 to 70 wt%. Despite a relatively lower selectivity of 75–59%, the amount of syndiotactic polystyrene in the presence of those catalysts was the greatest. Copyright © 2002 John Wiley & Sons, Ltd. |
