    摘要： A catalyst for the polymerization of olefins, containing magnesium, chlorine, aluminium and at least one transition metal, in a dispersed or emulsified form within an inert diluent, is obtained by:contacting, in an inert diluent, a magnesium dialkyl and aluminium trichloride, in a molar ratio equal or almost equal to 2/1, at a temperature lower than 105.degree. C. to obtain a catalyst precursor in a suspended form, or at a temperature higher than 105.degree. C. to form a catalyst precursor in the form of a colloidal emulsion, in the diluent used; andcontacting said suspended or emulsified precursor with at least one compound of a transition metal to form a catalyst in the form of a suspension or emulsion respectively.
