| titleOfInvention | A method of preparing polyimides |
| abstract | The invention discloses a kind of methods for preparing polyimides, belong to polymeric material field.The described method includes: diamines, dianhydride and blocking agent reaction obtain polyamic acid solution in the first polar solvent, the end-capping reagent is single acid anhydride containing active function groups, and the active function groups are that may occur from by the functional group of base polymerization reaction；Make the polyamic acid solution imidization and purify, obtains polyimide prepolymer；The polyimide prepolymer is dissolved in the second polar solvent, radical initiator is added, obtains mixed glue solution, the mixed glue solution is solidified, is cooled to room temperature and is removed, obtain the polyimides of film-form.The method is crosslinked the active group of end-capping reagent under low temperature, and Kapton is made to maintain the higher transparency, expands it in the application in flexible display material field. |
