A fluorine-containing copolymer comprising repeating units derived from an olefin of the formula: <CHEM> wherein R<1>, R<2>, R<3> and R<4> are the same or different and each a hydrogen atom or a fluorine atom, or one of them is a chlorine atom and the rest of them are fluorine atoms, and repeating units derived from a vinylphosphonic acid derivative of the formula: CF2=CF(CF2)n- @-(OR)2 (II) wherein R groups are the same or different and each an alkyl group having 1 to 12 carbon atoms, an alkenyl group having 2 to 12 carbon atoms or a phenyl group, and n is 0, 1 or 2, which has good hydrophilicity. |
