摘要：
Various zirconocene and titanocene complexes 1-8 effectively catalyze the polymerization of epsilon-caprolactone in a nearly living fashion at ambient temperature to afford poly-epsilon-caprolactone. The highest T.O.N. of 8000 was obtained at 70-75 degrees C with the agostic complex 8. (C) 1997 Elsevier Science Ltd.
