  • Patent number: 9012359
    Abstract: Activating supports may be suitably prepared by the following procedure (a) providing a porous mineral oxide support material, (b) treating the support with a phosphorus-containing compound, (c) treating the support from step (b) with an organometallic compound, (d) heating the functionalized support from step (c) under an inert gas and then under an atmosphere comprising oxygen, (e) fluorinating the support with a fluorinating agent, and (f) recovering an activating support. The activating supports are suitable used in combination with single site catalysts for the polymerization of olefins. The supports are most preferably used in combination with metallocene complexes. The preparative route for the activating supports provides for supported polymerization catalyst systems having excellent activities.

  • Patent number: 8796403
    Abstract: The present invention relates to copolymers with polar and non-polar olefin blocks with a variable polar monomer content of 0.1 mol % to 99.9 mol %. The invention also relates to a method for obtaining copolymers with olefin blocks and vinyl polar monomer blocks, said method using a single-component catalytic system made up of an organometallic complex containing a metal belonging to groups VIII to X. Said organometallic complex is advantageously active in the medium without adding cocatalyst.

  • Patent number: 8524627
    Abstract: The present invention relates to a process for preparing an activating support for metallocene complexes in the polymerization 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) functionalizing the support with a solution containing a metallic salt; IV) heating the functionalized support of step c) under an inert gas or hydrogen; V) oxidizing the support of step IV by treatment under N2O 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 polymerization of olefins.
