NOVELTY - A dichloroamino-functionalized polymer having a backbone chain comprising fluoroalkylene repeat units optionally substituted by ether oxygen, and a molar concentration of a molar concentration of 0.5 to 50 mol-% of repeat units, where the dichloroamino-functionalized polymer has no crystalline melting point above 180 degrees C that is associated with a latent heat of melting greater than 1 J/g.    USE - The dichloroamino-functionalized polymer is useful for imageable article used in photolithography, photovoltaics, electrowetting and microlens arrays.    ADVANTAGE - The fluoropolymer can be thermally treated to form crosslinked fluoropolymers with highly stable perfluoroalkylene crosslinks. The fluoropolymer is conveniently prepared by treating a cyano-functionalized fluoropolymer with Cl-F.    DETAILED DESCRIPTION - A dichloroamino-functionalized polymer having a backbone chain comprising fluoroalkylene repeat units optionally substituted by ether oxygen, and a molar concentration of a molar concentration of 0.5 to 50 mol-% of repeat units represented by Structure I, where the dichloroamino-functionalized polymer has no crystalline melting point above 180 degrees C that is associated with a latent heat of melting greater than 1 J/g.    x and z=0-3;    a and y=0-6;    R1=(CF2)aCFR2; and    R2 and R3=F or 1-6C perfluoroalkyl optionally substituted by ether oxygen with the proviso that y and z cannot both be zero; and, with the further proviso that no repeat unit in the backbone chain of the dichloroamino-functionalized polymer has more than two vinyl hydrogens attached to it.    INDEPENDENT CLAIMS are included for:    (1) a process involving combining, at a temperature in the range of 20-150 degrees C, chlorine (Cl)-fluorine (F) at a pressure with a cyano-functionalized polymer comprising fluoroalkylene repeat units optionally substituted by ether oxygen, and a molar concentration of a molar concentration of 0.5 to 50 mol-% of repeat units represented by Structure II; and    (2) a Cl-F addition process involving combining, at a temperature in the range of 60 to 80 degrees C, Cl-F at a pressure of 5 to 25 psig with a cyano-functionalized polymer having a backbone chain comprising repeat units of tetrafluoroethylene and perfluoromethylvinyl ether, and a molar concentration in the range of 0.5 to 5 mol-% of repeat units represented by Structure VI, where the cyano-functionalized polymer has no crystalline melting point above 150 degrees C that is associated with a latent heat of melting greater than 1 J/g.    .
