FIELD: chemistry of polymers. SUBSTANCE: claimed method for preparing olefin polymerization catalyst comprising magnesium, chlorine, aluminium and at least one transition metal in dispersed or emulsified form within inert diluent. The claimed method comprises contacting magnesium dialkyl and aluminium trichloride in inert solvent in about 2:1 molar ratio at temperature lower than 105 C to obtain catalyst precursor in suspended form, or at temperature higher than 105 C to obtain catalyst precursor in the form of colloided emulsion in diluent and contacting said suspended or emulsified catalyst precursor at least with one transition metal compound to form catalyst in suspension or emulsion form, respectively. EFFECT: more efficient preparation method. 10 cl
