Summary

Active centers have been studied in the polymerization of propylene using highly active Mg(OEt)2/Benzoyl chloride/TiCl4 catalysts activated with AlEt3. The method for the measurement of active centers is based on the inhibiting effect of CO on polymerization. The activity of the present catalysts, which is higher than that of TiCl3 or MgCl2-supported catalyst, is mainly due to the higher concentration of active centers by one order of magnitude. In order to investigate the stability of active centers during polymerization the number of active centers are compared at various polymerization times.
