| titleOfInvention | Process for preparing soluble polyimide copolymer |
| abstract | The present invention relates to a method for preparing a soluble polyimide copolymer, and more particularly, to a method for preparing a polyimide copolymer separator, in which a dianhydride and a diamine are polymerized in a solvent to form a precursor polyamic acid in a solution state. After the reaction, the reaction system temperature was rapidly increased to a temperature range of 160 to 200 ° C., imidized and dehydrated in a solution state, and then the viscous polyimide solution was cooled to room temperature. It is about. |
