The present invention provides a method for producing a stabilized fluoropolymer which comprises producing the stabilized fluoropolymer by subjecting a treatment target substance containing a sulfonic-acid-derived-group-containing fluoropolymer to a fluorination treatment, wherein the sulfonic-acid-derived-group-containing fluoropolymer is a fluoropolymer containing &#x2014;SOM (in which M represents H, NRRRRor M; R, R, Rand Rare the same or different and each represents H or an alkyl group containing 1 to 4 carbon atoms; and Mrepresents an L-valent metal), and the treatment target substance has a moisture content of not higher than 500 ppm by mass.

Stabilized fluoropolymer and method for producing same

A polymer electrolyte membrane comprising: (a) a fluorinated polymer electrolyte having an ion exchange group, and (b) a basic polymer, wherein, optionally, at least a part of component (a) and at least a part of component (b) are chemically bonded to each other. A method for producing the above-mentioned polymer electrolyte membrane. A membrane/electrode assembly comprising the above-mentioned polymer electrolyte membrane which is securely sandwiched between an anode and a cathode. A polymer electrolyte fuel cell comprising the membrane/electrode assembly.

Polymer electrolyte membrane having high durability and method for producing the same

A wrinkle-free organic film having a high light transmittance and a uniform film thickness is obtained by forming an organic thin film on the surface of a substrate having a contact angle of the surface to water of 90&deg; or higher, followed by peeling the film therefrom.
