Process for the preparation of a particulate bimodal polyethylene product |
| abstract |
The invention relates to a process for the preparation of a particulate bimodal polyethylene product having a median particle diameter of less than 300 μm in a serially connected double loop reactor, wherein said polymerization catalyst applied in the polymerization process comprises a particulate metallocene-alumoxane catalyst immobilized on a porous silica support, wherein said polymerization catalyst has a median particle diameter of less than 50 μm; and whereby the ratio of the median particle diameter of the obtained bimodal polyethylene product to the median particle diameter of the applied polymerization catalyst is less than 30. |
