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

## Abstract A supported magnesium‐vanadium‐aluminium catalyst was prepared by depositing –with the use of a milling technique–VOCl~3~ on the MgCl~2~(THF)~2~ support and subsequent activation with diethylaluminium chloride. Catalytic activity of the obtained system for ethylene polymerization was ev
