Abstract:
This invention pertains to an azo-crosslinked fluoropolymer with perfluoroether pendant groups. The polymer so formed is highly useful in the form of shaped articles with excellent chemical and thermal stability, including photoimaged coatings. The azo-crosslinked fluoropolymer hereof is advantageously formed by exposure to UV radiation of a fluorinated polymer having dichloroamino-functionalized perfluoroether pendant groups. In one embodiment, a fluorinated polymer having dichloroamino-functionalized perfluoroether pendant groups is formed into a shaped article that is then UV-treated in situ.
