Abstract:
1. A vinyl fluoride copolymer comprising: about 40 to about 69.9 mole % of repeat units derived from vinyl fluoride; and about 30.1 to about 60 mole % of repeat units derived from monomer 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) tetrafluoroethylene; 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 wherein at least about 30 mole % units of said vinyl fluoride copolymer are derived from tetrafluoroethylene.
