Abstract
Process for the treatment of a spherical catalyst for the polymerisation of olefins, containing at least one transition metal, a magnesium compound and a halogen, characterised in that ethylene is prepolymerised in the presence of the spherical catalyst, in the presence of a cocatalyst chosen from alkylaluminiums, at least partially in suspension, to a degree of prepolymerisation adapted to the polymerisation process in which the prepolymer will be subsequently used, a spheroprotector being used in combination with the various components not later than after the prepolymerisation, the accepted formula of the said spheroprotector being: AlR'mR''nClpHq in which 0.05 < p </= 1 0 < m < 2.95 0 < n < 2.95 0 </= q </= 1 it being known that m + n + p + q = 3 and R' and R'', which are identical or different, are linear, branched or cyclic hydrocarbon radicals containing from 1 to 14 carbon atoms. The catalyst thus treated conserves its spherical morphology in the subsequent polymerisation of ethylene. It is particularly suited for the manufacture of linear polyethylene powder with spherical morphology.
