Document Type and Number:
WIPO Patent Application WO/2023/008365
Kind Code:
A1
Abstract:
The present invention is a wholly aromatic ether ketone resin composition that includes (A) a prescribed wholly aromatic ether ketone resin and (B) a salt composed of an acid and a base, and that has a pH of 6-8 as measured through the following pH measurement method. [pH measurement method] (a) 5 mL of acetone is added to 10 g of a powder of the wholly aromatic ether ketone resin composition, after which 100 mL of pure water is added, the mixture is stirred for 10 minutes, and then filtration is carried out. (b) 0.1 mL of pure water is added dropwise to a residue generated by volatilizing the liquid components of the resultant filtrate. (c) The temperature is set at 25°C, and pH test paper is brought into contact with the dropwise-added pure water to measure the pH.
