摘要: Novel low molecular weight poly(ester amide)s based on glycine and l-lactic acid with interest for the biomedical field were successfully prepared by interfacial polymerization, which is an easy fast polymerization method. Preparation of α-amino diamine, diacyl chlorides was carried out in absence catalysts. The structure different confirmed 1H NMR Fourier transform infrared spectroscopies. thermal behaviour synthesized evaluated simultaneous analysis, differential scanning calorimetry dynamic mechanical analysis. It found that both incorporation oligomeric segment change its central unit have important influence characteristics amide)s. These novel can be used as building blocks preparation more complex structures. © 2013 Society Chemical Industry
