The results put forward a plausible deactivation reaction path of the catalyst for trimethylaluminum, while for methylaluminoxane and a novel phenoxyaluminum-based activator, the experimental catalyst's activity correlates with the energy barrier for the ethylene insertion. %G English %2 https://ifp.hal.science/hal-01070767/document %2 https://ifp.hal.science/hal-01070767/file/manuscrit_pout_HAL_IFPEN.pdf %L hal-01070767 %U https://ifp.hal.science/hal-01070767 %~ IFP
