摘要：

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 degreesC to produce polyethylenes (M-n:11000-41800) having narrow molecular weight distributions (M-w/M-n: 1.11-1.14, displaying very high activities (52-288 kg-PE/mol-Ti(.)h(.)atm).
