Abstract

Processo per la preparazione di copolimeri elastomerici dell'etilene, in cui si copolimerizza l'etilene con una ?-olefina, ed eventualmente con un diene come temonomero, in presenza di un catalizzatore Ziegler-Natta comprendente un componente solido di catalizzatore a base di titanio ed alluminio, supportato su cloruro di magnesio ed ottenuto, secondo un particolare procedimento, in forma di solido granulare sferico. Tale processo permette di ottenere copolimeri elastomerici caratterizzati da bassa cristallinità anche ad elevato contenuto di etilene legato.
