TECHNOLOGY FOCUS - POLYMERS - Preferred Polymer Composition: The polymer composition (in wt.%) comprises siloxane (10-15), and units of -OiSi(OH)4-i, where i is 1-4. Especially, the silane composition comprises organic polymer having pendant groups represented by formula (III) and silane comprising groups represented by formula (IV).-Op-(CF(Rf1)CF-Om)n-CF2CF2SO3M (III)(YO)bSiR13-bR2Rf2SO2Z (IV)Preferred Organic Polymer: The organic polymer is represented by formula (V). The organic polymer comprises pendant groups (3-10 mole%).Q1, Q2 = F or H;Rf1 = F or 1-10C perfluoroalkyl radical optionally substituted by one or more ether oxygen atoms, preferably CF3;Rf2, R1, R2 = same as that of groups in siloxane;X = H or M;M = alkali metal;Y = alkali metal or alkyl radical, preferably alkyl radical;Z = F or -OM, preferably F;c, d = at least 0;c+d = 4-199;m, p = 0 or 1, preferably 1;n = 0-3, preferably 1;Q1 = H, when d = at least 0 and Q2 = F; andQ1, Q2 = H when p = 0, Rf1 = F, X = H and m, n = 1.Preferred Process: The blend is contacted with a base having formula (MOH), where M is alkali radical. The blend is contacted with an acid. Preferred Definitions:    R2 = ethenyl;    Rf2 = -CF2CF2OCF2CF2-;    X = H;    Rf1 = trifluoromethyl;    m, p = 1;    n = 0 or 1; and    a, b = 3.    EXAMPLE - (In g) benzoyl peroxide (0.5) was added to a stir mixture of ICF2CF2OCF2CF2SO2F (85) and (CH3O)3SiCH=CH2 (32) at 90-95 degrees C in nitrogen atmosphere. The resulting mixture was stirred at 95 degrees C for 40 minutes. Benzoyl peroxide (0.5) was added and the mixture was stirred for 4 hours or more and then evacuated to remove excess starting materials. The mixture was cooled to room temperature, and (C4H9)3SnH (59) was slowly added and the mixture was stirred at room temperature overnight and distilled to give liquid (60.9) (CH3O)3SiCH2CH2CF2CF2OCF2CF2SO2F having a purity of greater than 99% and boiling point of 55 degrees C/3 mmHg.    Nafion (RTM; perfluoroionomer membrane of type 105 having thickness of 127 micrometer and equivalent weight of 1000) was created using the liquid. A solution of (CH4O)3SiCH2CH2CF2CF2OCF2CF2SO2F (5.2) and potassium hydroxide (5) in a mixture of methanol (10 ml) and water (8 ml) was prepared by stirring at room temperature for 2 hours. Two Nafion (RTM; perfluoroionomer membrane of type 105 having thickness of 127 mum and equivalent weight of 1000) were immersed in the obtained solution at room temperature for 5 minutes and dried at 100 degrees C for 5 minutes. The membranes were immersed in the solution again for 5 minutes, and dried at 100 degrees C for 5 minutes. The films were quickly washed with 4% hydrochloric acid again and dried at 80 degrees C in an oven overnight. The films were treated with 10% nitric acid at 70 degrees C for 2 hours, washed with deionized water and boiled in deionized water for 1 hour. Inductively Coupled Plasma (ICP) analysis showed that the film contained 0.36% silicon and conductivity was 0.13 S/cm.
