| titleOfInvention | Method for producing polyamic acid block polymer, method for producing liquid crystal aligning agent, liquid crystal aligning agent, liquid crystal alignment film, and liquid crystal display device |
| abstract | A method for producing a liquid crystal aligning agent excellent in storage stability at room temperature is provided, which does not lower the properties of the resulting liquid crystal aligning film and liquid crystal display element even when stored at room temperature for a long time. The present invention relates to a method for producing a polyamic acid block polymer, characterized in that a solution containing two or more polyamic acids is heated to 30°C or higher to undergo an amide exchange reaction. The heating temperature is, for example, 30 to 100°C. The heating time is, for example, 1 to 48 hours. The solution containing two or more types of polyamic acids is, for example, a solution obtained by synthesizing two or more types of polyamic acids alone and then mixing them. |
