SUPPORTED OLEFIN POLYMERIZATION CATALYST, ITS PREPARATION AND USE |
摘要 |
<p>Olefin polymerization comprising catalysts based on a metallocene, an alumoxane and a support are disclosed. The process for the preparation of a supported olefin ploymerization catalyst comprises:a) a metallocene/activator reaction product, a solvent capable of dissolving it, and a porous support are brought into mutual contact, andb) the solvent is removed,and wherein step a) is carried out so that the porous support is impregnated with a volume of the metallocene/activator reaction product and solvent, which does not exceed the total pore volume of the support.</p> |
