摘要：
Disclosed are catalysts for the polymerization of ethylene and of mixtures thereof with olefins, comprising the product obtained by reacting the following components:(a) an Al-alkyl compound;(b) an electron-donor compound containing at least a nitrogen atom, said compound being reactive towards MgCl.sub.2, but not towards Al-triethyl; and(c) the reaction product between a titanium compound containing at least a titanium-halogen bond and an anhydrous magnesium halide.The obtained (co)polymers have a very narrow molecular weight distribution which renders them particularly suitable for some applications, such as injection molding.
