Abstract:Ethylene polymerization by Cp 2 ZrCl 2 -B(C 6 F 5 ) 3 -TEA catalyst system using low Al/Zr ratio has been studied with varying ethylene pressure, catalyst concentration, Al/Zr ratio, and reaction temperature. The study showed that there was an optimum condition for each variable at which maximum productivity was obtained. It was proposed that there were two competing reactions, the catalyst activation and deactivation, taking place simultaneously. The maximum productivity of 3133 kgPE/mole-Zr.atm.h was obtaine… Show more
