Abstract Three new titanium complexes having two indolide-imine ligands were synthesized and investigated as ethylene polymerization catalysts. These complexes using MAO as a cocatalyst promoted ethylene polymerization at 25 °C to produce polyethylenes (Mn:11000–41800) having narrow molecular weight distributions (Mw/Mn: 1.11–1.14), displaying very high activities (52–288 kg-PE/mol-Ti·h·atm).
