## Abstract An ironโbased catalyst of 2,6โ__bis__โ[1โ(2โmethylphenylimino)ethyl]pyridine iron dichloride was prepared. The ligand was prepared using 2,6โdiacetylpyridine as the starting chemical under controlled conditions. The preparation procedure was followed using ^13^CโNMR, ^1^HโNMR, FTโIR, MS
Ethylene polymerization reactions with many Ziegler-Natta catalysts exhibit several features which differentiate them from polymerization reactions of โฃ-olefins: a relatively low ethylene reactivity, higher polymerization rates in the presence of โฃ-olefins, a high reaction order with respect to ethy
