Crosslinkable vinyl fluoride copolymers

A fluoropolymer blend comprising:

• a vinyl fluoride copolymer comprising:
• about 40 to about 90 mole % of repeat units derived from vinyl fluoride;
• and
• about 10 to about 60 mole % of repeat units derived from monomer selected from the group consisting of (a) and (b) below, with the proviso that about 0.1 mole % to 50 mole % of repeat units in said copolymer are derived from monomer selected from (b):
• (a) monomer selected from the group consisting of tetrafluoroethylene, trifluoroethylene, chlorotrifluoroethylene and mixtures thereof;
• and
• (b) fluorinated vinyl monomer containing at least one functional group selected from the group consisting of hydroxyls, thiols, carbonyls, carboxylic acids, carboxylic esters, acid anhydrides, sulfonyls, sulfonic acids, sulfonic esters, phosphoric acids, phosphoric esters, boric acids, boric esters, epoxies, isocyanates, thiocyanates, amines, amides, nitriles and halogen selected from bromide and iodide, wherein the functional group of said fluorinated vinyl monomer provides a crosslinkable reaction site;
• and at least one fluoropolymer different from said vinyl fluoride copolymer.
