摘要：A new poly(ester amide)s (PEA) derived from L-lactic acid and alpha-alanine have been synthesized by melting copolymerization with p-toluenesulfonic acid (TSA) with stannous chloride (SnCl2) as catalyst. The products were analyzed by NMR, FT IR techniques. The effects of the content of alpha-alanine (L-Ala) on the copolymers structure were studied. Being the phosphate buffered saline (pH=7.2) as the degradation solution, the degradation rate speed up with the increasing the content of the alpha-alanine.
