Abstract (en)

[origin: WO0212357A2] The invention concerns a method for preparing a catalyst support for homopolymerisation or copolymerisation of ethylene and alpha -olefins. Said method is characterised in that it consists in reacting, in the presence of at least an aliphatic diether as electron donor, at least a chlorinated organic compound and a prior mixture of at least an alkylmagnesium and at least an aluminium organic compound selected among aluminoxanes, aluminosiloxanes and alkylaluminiums.
