Summary:A process for preparing a solid catalyst component which comprises halogenating a magnesium compound in the formula MgRR .nCO2 in which R and R are the same or different alkoxy or phenoxy groups and n is a number of from 0 to 2 with a halide of tetravalent titanium in the presence of dialkylester of a dihydric aromatic carboxylic acid and an inert hydrocarbon diluent by reacting at a temperature of from 120 to 136 DEG C and recovering the solid reaction product from the reaction mixture.
