摘要

Fluorinated polymer (I), comprising repetitive units of formula (-CXY1-CZ(CH 2-O-Ar1-Q-G)-), is new. Fluorinated polymer (I), comprising repetitive units of formula (-CXY1-CZ(CH 2-O-Ar1-Q-G)-), is new. X, Y : H or F; Z : F or perfluoroalkyl; Ar1 : carbonated aromatic cycle (optionally substituted); Q : a bond, (CF 2) n (where, 1=n=10) or C 2F 4OC 2F 4; G : SO 2R 1, P(=O)(OR 2) 2 or CO 2H; R 1OH, F or Cl; and R 2H or alkyl (optionally substituted). Independent claims are also included for: (1) the preparation of (I); (2) a membrane (V) comprising (I); and (3) a fuel cell device comprising (V).
