摘要

用两种方法合成了聚酯酰胺（ＰＥＡ）共聚物．一种是两步法，即先合成对苯二甲酸乙醇酰胺（ＢＡＥＴ）单体，然后与对苯二甲酸乙二酯（ＢＨＥＴ）共缩聚；另一种是一步法．即在酯交换反应中直接添加乙醇胺（ＥＡ）．两种方法制得的聚酯酰胺（ＰＥＡ）共聚物测试证明了为产物，并分析了合成中的化学反应．

Abstract

The polyesteramide (PEA) is synthesized by two methods.One of them is two-step method

firstly BAET and BHET are synthesized from the reactions of DMT (dimethyl therephthalate) with EA (ethanolamine) and TPA(terephthalic acid) with EG (ethylene glycol)

reapectively;then BAET and BHET are condensation copolymerized.The chemical structure of the BAET is characterized by IR

IH--NMR and GC--MS.Another is one--step method that is synthesized by copolycondensation of DMT

EG and EA directly.All of the copolymers are characterized by the determination of nitrogen content

IR and NMR

The cha\emical reactions procssaes are discussed.
