A series of polyimides is prepared using 5-trifluoromethyl-1,3-phenylenediamine with dianhydrides of different structures.Polyamic acids prepared from this diamine are converted to imide films by thermal method.The polyimide films in most cases are ereasable and do not break on the fold line.Most polyimide films are in light color and soluble in m-cresol and DMAc.The polyimides have high glass transition temperature and thermostability.
- polyamic acid,
- polyimide,
