| Research Abstract |
It is difficult to design an efficient molecular catalyst for the ring-opening polymerization of lactones, because the balance of the molecular catalyst between Lewis acidity and nucleophilicity should be tuned to optimize the multistep process polymerization. In this research, a synergetic catalytic system for the ring-opening polymerization of.-caprolactone(CL) was developed. Both a Lewis acid and a nucleophile coexisted and the Lewis acid activated CL and the activated CL is attached by the weak nucleophile. In this system, independent tuning of the Lewis acidity and the nucleophilicity can be achieved.
