ABSTRACT:
The present invention is directed to a copolymer of a fluoromonomer having the formula R.sub.1 R.sub.2 C.dbd.CR.sub.3 F wherein R.sub.1, R.sub.2 and R.sub.3 are selected from H and F, and R.sub.3 may be Cl when R.sub.1 and R.sub.2 are F; and a vinyl monomer having the formula H.sub.2 C.dbd.CHR.sub.x, wherein R.sub.x is a radical having the formula --O.sub.2 CR.sub.y, wherein R.sub.y is a radical selected from CH.sub.3 and C.sub.2 H.sub.5.
The resulting copolymer comprises fluorinated units having the formula (R.sub.1 R.sub.2 C--CR.sub.3 F) wherein R.sub.1, R.sub.2 and R.sub.3 are selected from H and F, and R.sub.3 may be Cl when R.sub.1 and R.sub.2 are F, and corresponding amounts of vinyl units having the formula (H.sub.2 C--CHR.sub.x), wherein R.sub.x is selected from --CH.sub.3 and C.sub.2 H.sub.5. In an alternate and preferred embodiment the copolymer is hydrolyzed so that R.sub.x becomes --OH.
