Notes:
The different trends of polymerization rate as a function of time observed when polymerizing propene, ethylene and mixtures thereof in the presence of MgCl2-supported catalysts are explained assuming that catalyst deactivation is due to the reduction of Ti (III) by alkylaluminium to lower, polymerization-inactive oxidation states, and that ethyene polymerization is diffusion-controlled. A possible route for Ti reduction is also presented, which might give the reason for the observed kinetics of polymerization rate decay.
