Abstract

Viene fornito un metodo per la preservazione a lungo termine di componenti di catalizzatore solido di Ziegler-Natta per la polimerizzione di olefine costituiti essenzialmente di titanio, magnesio, un alogeno ed un donatore di elettroni, in anidride carbonica o in una atmosfera di gas inerte che contiene anidride carbonica, senza perdita della loro funzionalità.A method is provided for the long-term preservation of Ziegler-Natta solid catalyst components for the polymerization of olefins consisting essentially of titanium, magnesium, a halogen and an electron donor, in carbon dioxide or in an inert gas atmosphere which it contains carbon dioxide, without loss of their functionality.
