以对苯二胺、间苯二胺和3，3＇，4，4＇-联苯四甲酸二酐为单体，在低温条件下，通过缩合聚合得到高分子量的预聚体聚酰亚胺酸粘稠溶液，涂膜、热亚胺化后制得聚酰亚胺薄膜。通过FTIR、TGA及UV-Vis等对其结构和性能进行了表征。结果表明，聚酰亚胺薄膜具有优异的透明性、疏水性和力学性能，且对苯二胺型聚酰亚胺薄膜的力学性能高于间苯二胺型聚酰亚胺薄膜的力学性能。
以對苯二胺、間苯二胺和3，3＇，4，4＇-聯苯四甲痠二酐為單體，在低溫條件下，通過縮閤聚閤得到高分子量的預聚體聚酰亞胺痠粘稠溶液，塗膜、熱亞胺化後製得聚酰亞胺薄膜。通過FTIR、TGA及UV-Vis等對其結構和性能進行瞭錶徵。結果錶明，聚酰亞胺薄膜具有優異的透明性、疏水性和力學性能，且對苯二胺型聚酰亞胺薄膜的力學性能高于間苯二胺型聚酰亞胺薄膜的力學性能。

Polyamic acids( PAAs)with high molecular weight and viscous precursor solutions were syn-thesized by a condensation polymerization among p-phenylenediamine ( PDA ),m-phenylenediamine (MDA)and 3,3',4,4'-biphenyl tetracarboxylic diandhydride(BPDA)under low temperature. The cor-responding polyimide( PIs)films were prepared via coating and thermal imidization. The structure and properties of the PIs were characterized by FTIR,TGA and UV-Vis etc. The results showed that polyimide films had high transparency,good hydrophobic properties and excellent mechanical properties,and the PDA-based polyimide films possessed more excellent mechanical properties compared with MDA-based polyimide films.
