TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: The fluorine-containing silsesquioxane monomer is obtained by reacting fluorine-containing partially-condensed silsesquioxane of formula: (R-Si(OH)O2/2)l(R'-SiO3/2)m and reactive silane with polymerizable functional group. The fluorine-containing partially-condensed silsesquioxane is partially-condensed silsesquioxane having 1-6C fluoroalkyl group or fluoroether group. The polymerizable functional group of reactive silane is (meth)acryl group, ( alpha )-substituted acryl group, epoxy group or vinyl group, and reactive group chosen from trichlorosilyl group and 1-5C trialkoxysilyl group. The reactive silane is of formula: A11-A21-Si(A31)3. The monomer which does not contain fluorine atom has carbon-carbon double bond, and monomer which does not contain fluorine atom is (meth)acrylate having alkyl group or acrylate of formula: CH2=CA1COOA2. The crosslinkable monomer is compound having at least 2 reactive groups and/or carbon-carbon double bond, and does not contain fluorine atom, preferably compound having at least 2 carbon-carbon double bonds or at least one carbon-carbon double bond and at least one reactive group chosen from hydroxyl group, epoxy group, chloromethyl group, blocked isocyanate, amino group and carboxyl group.R,R'=Rf, Rf-A or 1-10C alkyl, at least one of R and R' is Rf or Rf-A;Rf=fluoroalkyl;A=1-4C alkylene, -SO2N(R21)R22- or -CH2CH(OH)CH2-;R21=1-4C alkyl;R22=1-4C alkylene;l,m=1 or more, preferably 2 or more;A11=polymerizable functional group;A21=direct bond or 1-20C alkyl;A31=chloro, bromo or 1-5C alkoxy;A1=H or methyl;A2=CnH2n+1;andn=1-30.Preferred Property: The partially-condensed silsesquioxane has number average molecular weight of 500-100000.    TECHNOLOGY FOCUS - POLYMERS - Preferred Composition: The fluoropolymer further has a structural unit derived from monomer which does not contain fluorine atom and optional structural unit derived from crosslinkable monomer. The polymeric group of fluorine-containing silsesquioxane monomer comprises carbon-carbon double bond.
