Synthesis and Characterization of Novel Aliphatic Poly(carbonate‐ester)s with Functional Pendent Groups

Summary: A novel cyclic carbonate monomer 5‐methyl‐5‐(succinimide‐ N ‐oxycarbonyl)‐1,3‐dioxan‐2‐one (MSTC) was prepared. The copolymers of MSTC with caprolactone (CL) were further synthesized by ring‐opening copolymerization. The copolymers with amido‐amine pendent groups were obtained by aminolysis of poly(MSTC‐ co ‐CL) with ethylenediamine. These copolymers were characterized by IR, 1 H NMR, 13 C NMR spectroscopies and GPC. The hydrophilicity and degradability of the copolymers with amido‐amine pendent groups were greatly improved in comparison with the PCL homopolymer. Hydrophilicity of PCL (1), poly(MATC‐ co ‐CL) (16.5:83.5) (2), and poly(MATC‐ co ‐CL) (29.5:70.5) (3). image Hydrophilicity of PCL (1), poly(MATC‐ co ‐CL) (16.5:83.5) (2), and poly(MATC‐ co ‐CL) (29.5:70.5) (3).
