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 MgC1 2 , but not towards AI-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.
The present invention relates to new catalysts for the polymerization of ethylene and of mixtures thereof with minor proportions of an alpha-olefin CH 2 =CHR wherein R is an alkyl radical having from 1 to 10 carbon atoms or an aryl. radical. Furthermore, it relates to the polymers obtained with said catalysts.-

摘要： Components of catalysts for the polymerization of ethylene and of mixtures thereof with olefins, in the form of emulsions or dispersions in an inert liquid medium or in inert gas phase of a liquid phase comprising a compound or composition containing a compound of the metals of the Groups IV to VI of the Periodic System, immiscible in aliphatic hydrocarbons or which components are obtained from emulsions or dispersions in an inert liquid medium or in gas phase of a precursor of the catalyst component, which in the liquid state is immiscible with the normal aliphatic hydrocarbons.
