β¦ Synopsis
A new iron-based catalyst, 2,6-bis[(1-naphthanylimino)ethyl]pyridine iron(II) chloride I, has been successfully synthesized and characterized. Ethylene was polymerized by I/methylaluminoxane to give branched, low-density polymers with good activity. The result shows that the new diimino ligand has improved the characteristics of the resulting polyethylene.

## Abstract An ironβbased catalyst of 2,6β__bis__β[1β(2βmethylphenylimino)ethyl]pyridine iron dichloride was prepared. The ligand was prepared using 2,6βdiacetylpyridine as the starting chemical under controlled conditions. The preparation procedure was followed using ^13^CβNMR, ^1^HβNMR, FTβIR, MS
The use of crosslinked poly(styrene-co-4-vinylpyridine) having functional groups as the support for zirconocene catalysts in ethylene polymerization was studied. Several factors affecting the activity of the catalysts were examined. Conditions like time, temperature, Al/N (molar ratio), Al/Zr (molar
