A series of diamines with various chlorine content was synthesized. Using these novel diamines, a series of new chlorinated polyimides was prepared by reacting them with 2,2‐bis(3,4‐dicarboxyphenyl)hexafluoropropane dianhydride (6FDA). The purpose was no investigate the effect of the chlorine content on the properties of polyimides, such as thermal and optical properties. The in‐plane refractive ( n TE ) indices of polymer films increase with increasing order of in‐plane orientation in these polyimides. The out‐of‐plane refractive ( n TM ) indices increase with chlorine content.
