    Abstract: The present invention relates to catalysts systems for the polymerization of ethylene and its mixtures with olefins CH
    2 =CHR, wherein R is an alkyl, cycloalkyl or aryl radical having 1-12 carbon atoms, comprising (A) a solid catalyst component comprising Ti, Mg, halogen, and optionally an electron donor compound in a donor/Ti molar ratio lower than 3, (B) an aluminum alkyl compound and (C) a silicon compound of formula X
    m R
    1
    n Si(OR
    2 )
    4-(m+n) in which X is bromine or fluoride or a halogen containing hydrocarbon group, R
    1 is a C1-C1O aliphatic or alicyclic group, R
    2 is C1-C1O alkyl group, m is an integer ranging from 1 to 3, n is 0 or 1 provided that the sum m+n is not higher than 3. The catalyst of the invention is suitably used in (co)polymerization processes of ethylene to prepare (copolymers having narrow Molecular Weight Distribution (MWD) and high activity.
