Beschreibung
Zusammenfassung:	The invention provides a polyimide polymer and a polyimide film. The polyimide polymer includes a repeating unit represented by a formula 1 shown in the description, wherein Ar is a tetravalent organic group derived from a tetracarboxylic dianhydride containing an aromatic group and a fluorine atom or a tetracarboxylic dianhydride containing an aromatic group and an oxygen group, and A is shown in description. The polyimide polymer and the polyimide film of the invention have good light transmittance, transparency and thermal stability. 本发明提供种聚酰亚胺聚合物以及聚酰亚胺膜，聚酰亚胺聚合物包括以式1表示的重复单元：其中Ar为衍生自含有芳香族基及氟原子或含有芳香族基及氧基的四羧酸二酐的四价有机基；以及A为本发明的聚酰亚胺聚合物以及聚酰亚胺膜具有良好的透光率、透明度及热稳定性。
