Summary

Copolymerization of ethylene with propylene was conducted over the thermally-reduced γ-Al2O3-supported TiCl4 catalyst both in the absence or presence of AlEt3 (or AlEt2Cl). It was found that the structure of the polymer drastically changed from a random copolymer to polyethylene with an increase in the concentration of AlEt3. A plausible mechanism was proposed for the copolymerization.
