Summary: | The present invention relates to a process for preparing an activating support for metallocene complexes in the polymerisation of olefins comprising the steps of:
I) providing a support consisting in particles formed from at least one porous mineral oxide;
II) optionally fixing the rate of silanols on the surface of the support;
III) functionalising the support with a solution containing a metallic salt;
IV) heating the functionalised support of step c) under an inert gas or hydrogen;
V) oxidising the support of step IV by treatment under N 2 O and then under oxygen;
VI) retrieving an active support having a controlled number of OH groups. That activating support is used to activate a metallocene catalyst component for the polymerisation of olefins. |
