TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The hydroxyl-containing monomer is chosen from hydroxyalkyl vinyl ether, polyethyleneglycol monovinyl ether, hydroxyalkyl allyl ether, polyethyleneglycol monoallyl ether, hydroxyalkyl vinyl carboxylate, hydroxyalkyl allyl carboxylate, hydroxyalkyl (meth)acrylate and/or hydroxyalkyl vinyl acetate. The dehydrating agent (B) is chosen from ortho acid ester, acetal and/or hemiacetal, preferably trimethyl orthoformate, triethyl orthoformate, 1,1-dimethoxyethane or 1-methoxy-1-ethanol. The organic solvent (D) is weak solvent. The antioxidant is chosen from phenolic antioxidant, phosphite-type antioxidant and thioether-type antioxidant. Preferred Compound: The hydroxyl-containing compound (A) is of formula: R-OH.R=1-6C hydrocarbyl.    TECHNOLOGY FOCUS - POLYMERS - Preferred Component: The silicon group-containing repeating unit (a2) is obtained by reacting monomer having silicon group-containing unit, isocyanate group-containing compound of formula: OCN(CH2)mSiXnR3-n and hydroxyl-containing monomer or obtained by reacting the isocyanate group-containing compound and hydroxyl-containing monomer. Preferred Composition: The fluoropolymer composition contains (in parts mass) fluoropolymer (A) (100), dehydrating agent (B) (1-30), hydroxyl-containing compound (C) (1-30), organic solvent (D) (10-100), and further contains antioxidant (E) (0.005-1 with respect to 100 parts mass of fluoropolymer (A)). The fluoropolymer (A) further has repeating unit (a3) having alkyl group, polymerizable unsaturated group and monomer bonded with ether linkage or ester bond and/or hydroxyl-containing repeating unit (a4). The content of fluoro-olefin-type repeating unit (a1) is 10-99 mol% with respect to total content of fluoro-olefin-type repeating unit (a1) and silicon group-containing repeating unit (a2). The total content of fluoro-olefin-type repeating unit (a1) and silicon group-containing repeating unit (a2) is 30-100 mol% with respect to total content of repeating units in the fluoropolymer (A). The content of silicon group-containing repeating unit (a2) is 1-90 mol%. The content of fluoropolymer (A) in the composition is 40-90 mass%.
