Abstract

Processo per la polimerizzazione in fase gas di olefine CH2=CHR in cui R è un atomo di idrogeno o un radicale alchilico o arilico contenente da 1 a 8 atomi di carbonio, condotta in uno o più reattori aventi un letto fluidizzato o agitato meccanicamente, usando un catalizzatore ottenuto per reazione di un alogenuro o aloalcolato di titanio ed eventualmente un composto elettron-donatore supportato su un dicloruro di magnesio attivo con un composto di alluminio trialchile ed eventualmente un composto elettron-donatore, comprendente gli stadi di: a) messa in contatto dei componenti del catalizzatore in assenza di olefine; b) prepolimerizzazione del propilene o di miscele di propilene con piccole quantità di etilene o di una alfa olefina per ottenere un polimero di propilene con una insolubilità in xilolo di almeno il 60% in peso, in quantità da 0,5 g per g di componente solido di catalizzatore fino al 10% in peso della resa finale del catalizzatore; c) polimerizzazione di una o più olefine CH2=CHR in fase gas in presenza del sistema prepolimero-catalizzatore ottenuto in b) mantenendo nel contempo in fase gas un alcano in concentrazione molare dal 20 al 90% rispetto al totale dei gas.
