Synthesis, Characterization, and Thermal Property of Functional

Abstract. A new approach for preparing polycaprolactone (PCL) with functional groups was introduced, by which three kinds of functional group-terminated PCLs (PCL-OH, PCL-Boc and PCL-NH2) were designed and synthesized. The composition, structure, and thermal property of these functional PCLs were characterized by FTIR, NMR and TGA. The results show that PCL-OH, PCL-Boc and PCL-NH2 were synthesized successfully. This new versatile synthetic platform can provide a large family of biodegradable, functional group-terminated copolyesters which are useful for the preparation of novel biodegradable polyester elastomer
