Abstract:The kinetics of the ring-opening polymerization of. -caprolactone with butane-1,4-diol as the initiator and 1,5,7-triazabicyclo[ 4.4.0] dec-5-ene as catalyst were examined. A highly efficient and controllable polymerization of. -caprolactone occurred with an activation energy of 22.5 kJ center dot mol-1, which is much lower than that observed with butan-1-ol as the initiator (39.5 kJ center dot mol-1). An intramolecular hydrogen- bonding-assisted mechanism is proposed to explain this lowering of the activation energy.
