ABSTRACT:
A process for making a supported Ziegler catalyst by (i) forming a support material by heating a magnesium carboxylate to convert it at least partially to magnesium oxide and (ii) impregnating said support material with product of reacting a halo-transition metal compound with an alcohol. The transition metal is Ti, V or Zr and the halo-compound is a halide, haloalkoxide, or oxyhalide. The catalyst can be activated using conventional Ziegler catalyst activations, e.g. triethyl aluminium.
