Abstract

Procedimento per la preparazione di LLPDE con migliorate caratteristiche di lavorabilità mediante polimerizzazione in fase gas operando in due o più reattori in cui, in un ordine qualsiasi, viene polimerizzata in un reattore una miscela di etilene e di una alfa olefina CH2 = CHR in cui R è un alchile con 1-10 atomi di carbonio a formare un copolimero contenente fino a ca. 20% in moli dell'alfa olefina e in un altro reattore viene polimerizzata una miscela di propilene e di una olefina CH2 = CHR' in cui R' e un radicale alchilico con 2-10 atomi di carbonio a formare un copolimero contenente da 5 a 40% in peso di detta olefina, in quantità di 5-30% sul peso totale del polimero.
