The effects of adding Al(i-C₄H₉)₃ (TEA) to rac-Me₂Si(Ind)₂ZrCl₂/MAO catalyzed propylene-1-octene copolymerization were studied. At TBA/MAO(Al/Al mole ratio) of about 0.6, the polymerization activity was found to be much higher than the system without TBA. In-creases of polymer molecular weight and 1-octene content from addition of TBA were also ob-served.
