TECHNOLOGY FOCUS - POLYMERS - Preferred Composition: The fluoropolymer further has a structural unit (B) derived from a monomer (b) which does not contain fluorine atom and a structural unit (C) derived from a cross-linkable monomer (c). The cross-linkable monomer (c) has reactive group and/or carbon-carbon double bond. Preferred Components: The polymerizable group of the monomer (a) is carbon-carbon double bond. The monomer (a) is obtained by reacting fluorine-containing partially condensed silsesquioxane (i) and reactive silane (ii) having polymerizable functional group. The fluorine-containing partially condensed silsesquioxane (i) is partially condensed silsesquioxane having 1-6C fluoro alkyl group or fluoro ether group. The fluorine-containing partially condensed silsesquioxane (i) is of formula: (R-Si(OH)O2/2)l(R'-SiO3/2)m. The polymerizable functional group of the reactive silane (ii) is (meth)acryl group, alpha-substituted acryl group, epoxy group or vinyl group. The reactive group of the reactive silane (ii) is trichloro silyl group and 1-5C trialkoxy silyl group. The reactive silane (ii) is of formula: A11-A21-Si(A31)3. The monomer (b) is monomer which does not fluorine and contains carbon-carbon double bond, preferably (meth)acrylic acid ester containing alkyl group. The monomer (b) is of formula: CH2=CA1COOA2.R,R'=Rf, Rf-A, 1-10C alkyl group or its derivative, where R and/or R' is Rf or Rf-A;Rf=fluoro alkyl group;A=1-4C alkylene group, -SO2N(R21)R22- or -CH2CH(OH)CH2-;R21=1-4C alkyl group;R22=1-4C alkylene group;l,m=1 or more, or 2 or more, and a number which becomes 500-100000 molecular weight of partially condensed silsesquioxane;A11=polymerizable functional group;A21=direct bond or 1-20C alkyl group;A31=halogen such as chlorine atom or bromine atom, or 1-5C alkoxy;A1=H or methyl;A2=CnH2n+1;andn=1-30.The cross-linkable (c) is compound having at least 2 carbon-carbon double bonds or carbon-carbon double bond(s), and reactive group(s). The reactive group of the monomer (c) is hydroxyl group, epoxy group, chloromethyl group, blocked isocyanate, amino group, or carboxyl group. EXAMPLE - 2.6 M 3F-silsesquioxane triol sodium hydroxide aqueous solution (0.3 L) and tetrahydrofuran (0.5 L) were mixed and stirred at 64degreesC. 3,3,3-trifluoro propyl trichlorosilane (50 g)/tetrahydrofuran (0.5 L) solution was dropped into the resulting solution for 1 hour. The resulting mixture was heat-refluxed and cooled to room temperature. The precipitated viscous material was removed by filtration. The resulting product was dried at reduced pressure. Tetrahydrofuran was added to the resulting product, and precipitated substance was removed by filtration. The resulting filtrate was concentrated and dried, to obtain white solid. The obtained white solid, tetrahydrofuran (0.6 L) and 35% tetraethyl ammonium hydroxide solution (40 g) were stirred at 64degreesC. The resulting mixture was heat-refluxed for 4 hours and cooled to room temperature. Perfluoro isohexane was added to the cooled solution after distilling tetrahydrofuran. 0.1 M hydrochloric acid was added to the resulting solution. The precipitated substance was removed by filtration. The white precipitate was recrystallized in perfluoro isohexane, to obtain white crystals of 3F-silsesquioxane triol (20 g). The obtained 3F-silsesquioxane homopolymer (in g) (5) and methyl isobutyl ketone (5) were mixed, and heated at 75-85degreesC for 10 minutes, to obtain liquid (A). Pure water (14.4), polyoxyethylene alkyl ether as nonionic emulsifier (0.5) and alpha-olefin sulfonic acid sodium salt as anionic emulsifier (0.1) were mixed and heated at 75-80degreesC for 10 minutes, to obtain liquid (B). The liquids (A and B) were mixed and emulsified. Water (98) was added to resulting emulsion (2), to obtain a process liquid. The obtained process liquid was applied on carpet. The processed carpet had excellent water repellence, oil repellence, stain resistance, heat resistance, weather resistance and wear resistance.
