摘要: 用热分析方法得出,由芳香酸甲酯或乙酯与4,4'-二氨基二苯甲烷制备的铵盐的酰胺化,酰亚胺化反应,较芳香酸的铵盐更易进行,反应温度和表观活化能均比四酸铵盐时低。由铵盐生成的聚酰亚胺具有很好的热氧化稳定性。

Abstract: The amidation and imidization processes of some aromatic tetracarboxylic esters with 4,4'-diaminodiphenyl methane have been studied by thermal analysis.The reaction tempera-tures and apparent activation energies for both reactions were found to be lower than thosefor the corresponding free acids with diamine used.Polyimides obtained from ammoniumsalts showed good thermal stability.
