Carrier for olefin polymerization catalysts |
| abstract |
Procedure for the preparation of a solid carrier for olefin polymerization catalysts, comprising the steps: n a) impregnating a silica with a solution of Mg-chloride in the presence of electron donors, n b) drying the impregnated silica obtained in (a) and impregnating it with a solution of Mg-alkyls in SiCl 4 at a temperature from -10 to 20° C., optionally adding a further amount of electron donors, n c) subsequently treating the slurry obtained in (b) at a temperature from 40° C. to reflux temperature, n d) drying the carrier obtained in (c). |
