Abstract
A series of random polyesteramides (PEAs) based on epsilon-caprolactone and glycine were synthesized by a direct melt polycondensation method. Their structure was fully characterized by NMR spectroscopy. High molar mass PEAs were obtained for glycine contents lower than 15 mol-%. The resulting copolymers are semi-crystalline and present increasing glass transition temperatures but decreasing melting points at increasing glycine contents. Some of these PEAs exhibit better thermal stability and higher Young's modulus and ultimate tensile strength than PCL homopolymer. (c) 2014 Wiley Periodicals, Inc. J. Appl. Polym.
