Patent

CA 2407644

The present invention provides a monomer having the formula A-B, wherein A is represented by Formula I:wherein B is selected from -OCF=CF2 and -A; wherein, when B is -OCF=CF2, the orientation of B is meta or para to the trifluorovinyloxy group of A; wherein, when B is A, the bond joining the A groups is para to the trifluorovinyloxy group of each A; and wherein each Z is independently selected from -SO2F, -SO2Cl, -SO3H, -SO2-N(M)-SO2CF3, and -SO2- N(M)-SO2Rf ; wherein M is any suitable cation and Rf is a C1 to C10 fluorocarbon or fluorinated ether group. The present invention also provides a monomer according to Formula II:wherein X is F, Cl, or N(M)SO2Rf; wherein M is any suitable cation and Rf is a C1 to C10 fluorocarbon or fluorinated ether group.

La présente invention concerne un monomère de formule A-B, dans laquelle A est représenté par la formule I ; B est pris dans -OCF=CF2 et -A; dans laquelle, lorsque B est -OCF=CF2, l'orientation de B est méta ou para relativement au groupe trifluorovinyloxy de A; dans laquelle, quand B est A, la liaison entre les groupes A est para relativement au groupe trifluorovinyloxy de chaque A; et dans laquelle chaque Z est pris indépendamment dans -SO2F, -SO2Cl, -SO3H, -SO2-N(M)-SO2CF3, et -SO2-N(M)-SO2Rf; dans laquelle M est n'importe quel cation convenable et Rf est un fluorocarbure en C1-C10 ou un groupe éther fluoré. Cette invention concerne également un monomère représenté par la formule II dans laquelle X est F, Cl, ou N(M)SO2Rf; M est n'importe quel cation convenable et Rf i est un fluorocarbure en C1-C10 ou un groupe éther fluoré.
