硫醚型芳香族二胺单体的合成及应用

Synthesis Application of a Aromatic Diamine Monomer

以对氨基硫酸及４，４＇－二氯基二苯砜为原料合成了含硫醚键芳香族二胺单体：，用它制备的聚酰亚胺显示了良好的耐热性能。

y using 4-aminothiophenol and 4-chlorobenzene sulfonyl chloride as raw materials, a diamine monomer was synthized. A polyimide possessing good thermal stability can be obtained from the reaction of the diamine monomer with pyromellitic dianhydide.
