摘要: 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; Vl) 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.-

摘要: The present invention discloses activating supports based on perfluorinated boronic acids and aluminium alkyls and their use in the activation of metallocene and post- metallocene complexes for the polymerisation of ethylene and alpha-olefins.
