Abstract
Ethylene polymerization using iron(II)bis(imino)pyridyl and Ni(diimine) catalysts was studied. The effect of the experimental parameters such as the nature of alkylaluminums, Al/M ratio and the temperature on the kinetics of polymerization, catalyst activity, molecular weights and molecular weight distributions of the polymers were explored. Whereas MAO and TMA gave broad molecular weight distributions, TIBAL and TIBDAO were found to produce narrow molecular weight distributions. DEAC is a non-activator for the Fe catalyst, but it is an effective cocatalyst for the Ni catalyst.
