Catalysts for the preparation of elastomeric olefinic copolymers |
| abstract |
Catalysts for the preparation of copolymers of ethylene and/or alpha-olefins and optionally dienes, are obtained by reacting an Al-alkyl with a solid catalytic component comprising: (A) a magnesium compound containing at least an Mg-halogen bond; (B) a halogenated compound of at least partly trivalent Ti or V, containing at least a Ti-OR or V-OR bond, wherein the Mg/Ti(V), halogen/Ti(V), halogen/Mg and OR/Ti(V) atomic ratios are within determined ranges; and (C) an electron-donor compound. Elastomeric copolymers endowed with improved tension set values are obtained with said catalysts. |
