The present invention is directed to a copolymer of a fluoromonomer having the formula R1R2C=CR3F wherein R1, R2 and R3 are selected from H and F, and R3 may be Cl when R1 and R2 are F; and a vinyl monomer having the formula H2C=CHRx, wherein Rx is a radical having the formula -O2CRy, wherein Ry is a radical selected from CH3 and C2H5. The resulting copolymer comprises fluorinated units having the formula (R1R2C-CR3F) wherein R1, R2 and R3 are selected from H and F, and R3 may be Cl when R1 and R2 are F, and corresponding amounts of vinyl units having the formula (H2C-CHRx), wherein Rx is selected from -CH3 and C2H5. In an alternate and preferred embodiment the copolymer is hydrolyzed so that Rx becomes -OH. |
