    • It is an object of the present invention to provide a liquid composition which comprises an acid/acid salt group-containing polymer and from which cured articles excellent in mechanical characteristics and undergoing only slight dimensional changes depending on the moisture content can be produced by application thereof to a substrate or impregnation of a porous material therewith. The present invention relates to a fluoropolymer liquid composition comprising a fluoropolymer liquid (A) which comprises a liquid medium and a crosslinkable functional group-containing crosslinkable fluoropolymer, wherein said fluoropolymer liquid (A) is a fluoropolymer liquid dispersion (AD) having, dispersed in a liquid dispersion medium, particles of a crosslinkable fluoropolymer (PD) containing acid/acid salt groups or organic groups capable of undergoing hydrolysis and thus being converted to carboxyl groups, or a fluoropolymer solution (AS) having, dissolved in a fluorosolvent or an alcohol/water mixed solvent, a crosslinkable fluoropolymer (PS) containing acid/acid salt groups or acid/acid salt groups precursors; said acid/acid salt groups are sulfonic acid groups, carboxyl groups or groups of the formula —SO2NR2R3, —SO3NR4R5R6R7, —SO3M11/L, —COONR8R9R10R11 or —COOM21/L, wherein R2 represents a hydrogen atom or M51/L, R3 represents an alkyl group or an sulfonyl-containing group, R4, R5, R6, R7, R8, R9, R10 and R11 are the same or different and each represents a hydrogen atom or an alkyl group, and M1, M2 and M5 each represents a metal having a valence of L, said metal having a valence of L being a metal belonging to the group 1, 2, 4, 8, 11, 12 or 13 of the periodic table; and said acid/acid salt groups precursors are —SO2F, —SO2NR22R23 (wherein R22 and R23 are the same or different and each represents an alkyl group) or organic groups capable of undergoing hydrolysis and thus being converted to carboxyl groups.

    • A segmented polymer comprising a sequence of two or more polymer segments, an iodine atom liberated from an iodinated compound bonded at a terminal position of said sequence and a fragment of the iodinated compound from which at least one iodine atom has been removed bonded at another terminal position of said sequence, whereby said sequence intervenes between said iodine atom and said fragment, wherein adjacent polymer segments are different in steric configuration or monomeric composition, at least one of said polymer segments containing fluorine and each polymer segment having a molecular weight of not less than 10,000 but at least one polymer segment having a molecular weight of not less than 30,000. The polymer may contain additional moieties which originate from the monomers which constitute the polymer segments and from the iodinated compound, when the latter has a polymerizable double bond. The segmented polymers are prepared in a sequence of steps involving radical polymerization.
