加熱等てこの脱酢酸が促進されることである。However, one of the drawbacks of this polymer is the desorption of acetic acid from the polymer, resulting in generation of acetic acid, deterioration of electrical properties, or discoloration, corrosion, or corrosion of metals in contact with these or surrounding metals. This is due to changes in long-term characteristics. In this regard, acetic acid removal inhibitors, prevention methods, scavengers, capture methods, etc. have been proposed, but at present, nothing effective has been found. These deacetic acid treatments have the inconvenience of occurring even in a normal practical atmosphere, but there are other ways to remove acetic acid, such as chemical crosslinking treatment using a radical generator, high-energy irradiation such as a Shizuko beam, and significant heating. is to be promoted.
