Fluorocopolymers for coating applications

A fluorocopolymer formed by copolymerization of:

• (1) haloolefin monomers consisting essentially of:
• (a) hydrofluorolefin selected from the group consisting of hydro fluoroethy1enes, hydrofluoropropenes, hydrofluorobutenes, hydrofluoropentenes and combinations of these, and
• (b) one or more chlorofluoroethylene monomers wherein the mole ratio of said hydrofluoroolefin monomer to said chlorofluoroethylene monomers monomer is from about 0.5:1 to about 1.5:1;
• and
• (2) alkyl vinyl ether monomer(s) and/or alkyl vinyl ester monomers consisting essentially of:
• (a) one or more lower alkyl vinyl ether monomers that are not substituted with a reactive group;
• and
• (b) one or more reactive group substituted lower alkyl vinyl ether monomer(s) and/or one or more reactive group substituted, lower alkyl vinyl ester monomer(s), wherein the mole ratio of (2)(a) monomers to said (2)(b) monomers is from about 2:1 to about 6:1, and
• (3) optionally one or more alkyl vinyl ester monomers that do not contain a reactive group substituted thereon, wherein the mole ratio of said haloolefin monomers to said alkyl vinyl ether monomer(s) is from about 0.5:1 to about 1.5:1.
