| titleOfInvention | Method for producing carboxylic acid dihalide, method for producing polyimide precursor, and method for producing cured product |
| abstract | A process for producing a carboxylic acid dihalide, a process for producing a polyimide precursor, and a process for producing a cured product using the production process are provided. A method for producing a polyimide precursor includes halogenating a compound having two or more carboxy groups with a halogenating agent to obtain a carboxylic acid dihalide, and reacting the carboxylic acid dihalide with water. and reacting the carboxylic acid dihalide with a diamine. [Selection figure] None |
