Abstract:
This invention pertains to a novel perfluoroalkyl-crosslinked fluoropolymer with perfluoroether pendant groups. The perfluoroalkyl-crosslinked fluoropolymer hereof is particularly well-suited for use in chemically and thermally aggressive environments, in part by virtue of the highly stable perfluoroalkyl crosslink. The perfluroalkyl-crosslinked fluoropolymer hereof can be prepared by crosslinking in situ a crosslinkable precursor in the form of a shaped article. A crosslinkable precursor is a fluoropolymer having a dichloroamino-functionalized functionalized perfluoroether pendant group.
