摘　　要：以盐酸苯胺为催化剂,对羟基苯甲醛与苯胺通过缩合反应,合成4,4'-二氨基-4"-羟基三苯基甲烷(DAHTM)单体。DAHTM单体与均苯四甲酸二酐(PMDA)聚合反应,得到含羟基的聚酰胺酸(DAHTM/PM-DA-PAA)溶液,经涂膜,热亚胺化后,制成相应的聚酰亚胺薄膜,并对其表面性能进行了研究。The monomer of 4,4＇-diamino-4＂- hydroxytriphenylmethane（DAHTM） was synthesized through the condensation reaction between p-hydroxy benzaldehyde（PHBA） and aniline in the presence of aniline hydrochloride as a catalyst. The hydroxyl containing polyamic acid（DAHTM/ PMDA-PAA） solution was obtained by the polymerization between DAHTM and PMDA. The corresponding polyimide film was prepared by thermal imidization of the DAHTM/PMDA-PAA thin layer, and its surface properties were also studied in this paper.
