Abstract

Un procedimento per polimerizzare etilene ad alta temperatura sotto pressione elevata, il quale comprende il porre in contatto l'etilene da solo o insieme con una alfa-olefina ad una temperatura di 120°C o maggiore ad una pressione di 350 kg/cm2 o più con un catalizzatore costituito essenzialmente da (A) un prodotto di reazione di (A1) un composto di titanio avente almeno un legame di titanio-azoto con (A2) un composto metallorganico di un elemento dei gruppi I-III della Tavola Periodica e (B) un composto di alluminio organico. Detto procedimento permette la produzione di un polimero etilenico o copolimero avente una ristretta distribuzione di composizione ed un elevato peso molecolare e che è eccellente per la resistenza agli agenti atmosferici, per lo sviluppo di colore, la trasparenza, la corrosività e le proprietà meccaniche.
