    Abstract: A method is provided for converting a polyimide to the corresponding polyamide acid salt, utilizing a predetermined amount of a strong base. The polyamide acid salt can be converted to the corresponding polyamide acid. The polyamide acids and polyamide acid salts provided by the subject method can be converted to the polyimide state after being applied to various substrates by standard dipcoating and electrocoating techniques. When utilized with a potentiometric titrator, the method of the invention also can be used to determine imide functionality of polyimide.

    Abstract translation: 提供了一种利用预定量的强碱将聚酰亚胺转化为相应的聚酰胺酸盐的方法。 聚酰胺酸盐可以转化为相应的聚酰胺酸。 通过本方法提供的聚酰胺酸和聚酰胺酸盐在通过标准浸涂和电泳技术施加到各种基材之后可以转化为聚酰亚胺状态。 当与电位滴定仪一起使用时,本发明的方法也可用于测定聚酰亚胺的酰亚胺官能度。
