Abstract
The present invention relates to catalysts for the polymerization of ethylene and its mixtures with olefins CH,═CHR,, comprising the reaction product of a solid catalyst component containing Ti, Mg and halogen, an alkyl-Al compound and a particular electron donor compound selected from the compounds containing at least two oxygen atoms bonded to different carbon atoms and selected by standard tests of reactivity with triethyl-Al and MgCl,compounds. The catalyst of the invention are used in processes for the (co)polymerization of ethylene to prepare (co)polymers having narrow molecular weight distribution (MWD).
