Abstract

Viene descritto un procedimento per la preparazione di un componente solido di catalizzatore attivo nella (co) polimerizzazione dell'etilene e capace di produrre (co) polimeri dell'etilene con distribuzione da media ad ampia del peso molecolare e con distribuzione monomodale dei pesi molecolari, nei procedimenti che operano in stadio unico, in sospensione o in fase gassosa. Detto componente solido di catalizzatore contiene magnesio, cloro, silicio, titanio ed almeno un'altro metallo di transizione su un supporto solido, granulare e poroso, e viene ottenuto trattando il supporto, in successione, con un composto di un metallo scelto tra afnio, zirconio o vanadio; un magnesio dialchile o magnesio alchil alogenuro; un cloruro di silicio; ed un composto di titanio.
