  • Activating supports based on phosphonium complexes
    Patent number: 8338324
    Abstract: The present invention relates to the covalent anchorage of non-coordinating anions on mineral supports to prepare activating supports for the polymerisation of ethylene and alpha-olefins and wherein the activating species is provided by a phosphonium-borate or phosphonium alane pair. The invention also discloses the concomitant covalent anchorage of zwitterionic systems containing both the non-coordinating anion and the counter cation parts of the activating supports.
