Ethylene (co)polymerization process

Ethylene is homopolymerized, or copolymerized with an alpha-olefin, in the presence of a catalytic composition formed from: i) a solid catalyst component (procatalyst), containing titanium, vanadium and chlorine in the following molar proportions: Ti (1), V (0.3-3), Cl (4-12); ii) a trialkylaluminiu...

Zusammenfassung:	Ethylene is homopolymerized, or copolymerized with an alpha-olefin, in the presence of a catalytic composition formed from: i) a solid catalyst component (procatalyst), containing titanium, vanadium and chlorine in the following molar proportions: Ti (1), V (0.3-3), Cl (4-12); ii) a trialkylaluminium or an alkylaluminium chloride cocatalyst; and iii) an activator chosen from particular classes of organic chlorine derivatives.
