Abstract:
1. A curable fluorine-containing polymer having a hydrolyzable metal alkoxide moiety which has a number average molecular weight of from 500 to 1,000,000 and is represented by the formula (2): wherein the structural unit M is a structural unit derived from a fluorine-containing ethylenic monomer having a hydrolyzable metal alkoxide moiety and represented by the formula (M): in which X wherein —D— is a fluoroether unit represented by the formula (D): in which n is an integer of 1 to 20; R is at least one selected from fluorine-containing divalent alkylene groups having 1 to 5 carbon atoms where at least one of hydrogen atoms is replaced by fluorine atom, and R may be the same or different when n is not less than two; Ry is a hydrocarbon group having 1 to 39 carbon atoms where a part or the whole of hydrogen atoms are replaced by fluorine atoms or a hydrocarbon group having 1 to 99 carbon atoms and ether bond where a part or the whole of hydrogen atoms are replaced by fluorine atoms, which is an organic group in which one to three of hydrogen atoms are replaced by Y the structural unit N is a structural unit derived from a fluorine-containing ethylenic monomer and represented by the formula (N): in which X the structural unit A is a structural unit derived from a monomer being copolymerizable with the fluorine-containing ethylenic monomers providing the structural units represented by the formulae (M) and (N), and the structural units M, N and A are contained in amounts of from 0.1 to 100% by mole, from 0 to 99.9% by mole and from 0 to 99.9% by mole, respectively.
