## 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
## Abstract Spherical MgCl~2~·nEtOH was prepared by adducting ethanol to MgCl~2~ using melt quenching method. Effect of molar ratio of [EtOH]/[MgCl~2~] = 2.8–3.05 on the morphology and particle size of the MgCl~2~·nEtOH were studied. The best adduct of spherical morphology was obtained when 2.9 mol
