description The invention relates to catalyst components, suitable for the preparation of homopolymers and copolymers of ethylene having a broad molecular weight distribution (MWD), which comprise Ti, Mg, Cl, and are characterized by the following properties: surface area, determined by BET method, of lower than 100 m /g, a total porosity, measured by the mercury method, of higher than 0.25 cm /g, a pore radius distribution such that at least 45% of the total porosity is due to pores with radius up to 0.1 mum.
