A solid catalyst component for the low-pressure polymerization of ethylene and C3-C10 alpha-olefins into very high molecular weight polyolefins is in the form of a spherical granular solid having a surface area of between 20 and 40 m2/g, a mean pore radius of between 5,000 and 40,000 A and a porosity of between 40 and 90 vol %, and is definable by the following formula (in atomic proportions): X (1), Mg (1-8), Al (0.2-0.8), Cl (5-20), (Et+OEt+OR) (1-3); where: X = Hf or Zr; Et = ethyl group; OEt = ethoxy group; and OR = alkoxy group containing from 2 to 8 carbon atoms in the linear or branched alkyl portion. Such a catalyst component is obtained by preparing a solid spherical granular support by spray-drying an ethanolic solution of magnesium chloride, reacting said support with a hafnium or zirconium alkoxide or halogenalkoxide, and finally reacting the thus treated support with an alkyl aluminium chloride.
