摘要: The present invention relates to catalysts for the polymerization of ethylene and its mixtures with olefins CH2=CHR, wherein R is an alkyl, cycloalkyl or aryl radical having 1-12 carbon atoms, comprising (A) a solid catalyst component Ti, Mg, halogen, optionally electron donor compound in donor/Ti molar ratio lower than 3, (B) aluminum alkyl (C) silicon formula: RmSi(OEt)n which C1-C20 group, m integer ranging from 1 n (4-m) proviso that when equal to, higher than, C3 2. suitably used (co)polymerization processes prepare (co)polymers narrow Molecular Weight Distribution (MWD) high activity.
