T. Matsugi et al., New titanium complexes having two indolide-imine chelate ligands for living ethylene polymerization, CHEM LETT, (6), 2001, pp. 566-567
Three new titanium complexes having two indolide-imine ligands were synthes
ized 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 d
istributions (M-w/M-n: 1.11-1.14, displaying very high activities (52-288 k
g-PE/mol-Ti(.)h(.)atm).
