摘要
采用邻苯二甲酸酐、二乙醇胺为原料,先在冰水浴条件下,合成AB2型单体,然后进行熔融缩聚制得水溶性超支化聚(酰胺-酯),使用吡啶对羧基进行保护,避免了反应中出现凝胶现象.应用红外谱图对改性的超支化聚(酰胺-酯)进行了分析,用十八酸作封端剂对超支化聚(酰胺-酯)进行端基改性.结果表明,产品的红外谱图中没有出现羟基吸收峰,说明产品的端羟基成功地进行了酯化反应.
This paper presents the synthesis of a kind of hyperbranched poly(amide-ester).The AB_2 type monomer was synthesized by use of o-phthalic anhydride and diethanolamine under the condition of ice-bath,a kind of water-soluble hyperbranched poly(amide-ester) was synthesized by heating,the pyridine was used to protect the carboxylic group,gelation was avoided.Stearic acid was used as capping agent of the hyperbranched poly(amide-ester),IR spectrum testified the reaction.
