## Abstract **Summary:** The effective immobilization and activation of a single‐site chromium catalyst for ethylene polymerization has been achieved using MgCl~2~/AlR~__n__~(OEt)~3β€‰βˆ’β€‰__n__~ supports, without the use of methylaluminoxane (MAO) or a borate activator. High catalyst activity and a sph
