  • Reactor continuity
    Patent number: 8846811
    Abstract: A dual catalyst system comprising a phosphinimine ligand containing catalyst and phenoxide ligand (preferably a salicylaldimine) on a support treated with a metal salt has improved reactor continuity in a dispersed phase reaction in terms of initial activation and subsequent deactivation The resulting catalyst has a lower consumption of ethylene during initiation and a lower rate of deactivation. Preferably the catalyst is used with an antistatic agent.
