Titanium catalysts based on calixarene ligands have been prepared and screened for their performance as ethylene polymerisation catalysts. Upon methylaluminoxane (MAO) activation, some of these systems displayed high activity for the production of high-density polyethylene. Both the Ti coordination mode and the ligand conformation have been found to be significant for the catalytic performance.
