摘要/描述

A new kind of polyesteramide copolymer based on e-caprolactone and 11-aminoundecanoic acid has been synthesized by melt polycondensation. The copolymers were characterized by FTIR, 1H-NMR, DSC, and WAXD. With the increase in aminoundecanoic acid content, the melting temperature, heat of fusion, and Td,50% increased accordingly. The thermal degradation of the P(CL/AU)x/y copolymers was studied using FTIR, and TG During thermal degradation, the ester bond decomposes at lower temperature, then the amide bond decomposes at higher temperature.
