خلاصه مقاله:
Bis(indeneyl)zirconium dichloride, (Ind)2ZrCl2, catalyst was synthesized and used for copolymerization of ethylene and propylene (EPR) and, terpolymerization of ethylene propylene and 5-ethyldiene-2-norbornene (ENB). Methylaluminoxane (MAO) was used as cocatalyst. Activity of The catalyst was higher for the copolymerization of ethylene and propylene (EPR) than ethylene propylene and diene monomer terpolymeization(EPDM). The effect of [Al]/[Zr] ratio, temperature, relative pressure of E/P and the ENBconcentration on the polymerization behavior were studied.
