We presented the results of propylene polymerization-kinetics on complex-catalysts obtained from reduced TiCl4
by complexation of AlEt2Cl and. isoamyl ether. The characteristics of reacting kinetic curves of polymerization were measured in the normal pressure. The rate constant
reaction order 'and activation energy were measured and rate equation
r=KGP
was developed. Experimental data of the stereoregularity of polymer was discussed in the light of the kinetic behavior of the catalyst System.
