ABSTRACT OF THE DISCLOSURE A process for the homopolymerization or copolymerization of olefins is disclosed. The process is carried out in the presence of a catalyst system comprising the combination of an organometallic compound with a component resulting from the mutual contact of (i) and inorganic magnesium compound of a spherical shape having an average particle size of from 1 to 100 microns; (ii) a compound represented by the formula A1X3-OR'R" (where X represents a halogen atom, and R' and R" represent a hydrocarbon residual group having 1 to 20 carbon atoms; and (iii) a titanium compound represented by the formula Ti(OR)4 (where R represents a hydrocarbon residual group having 1 to 20 carbon atoms). The resulting polymers are provided with a spherical particle shape.
