TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Groups: The ion exchange group is in the form of salt of acidic group, and is preferably sulfonic acid group, phosphinic acid group, phosphonic acid group, carboxyl group, or salts of the above mentioned acidic groups.    TECHNOLOGY FOCUS - POLYMERS - Preferred Method: The cured material is further subjected to acid treatment before or after cutting.The gel or sol is obtained by performing hydrolysis and polycondensation reaction of silanized compound (A) of formula: RmSi(OR')4-m, and silanized compound (B) of formula: XnSi(OR)4-n simultaneously.R, R' and R = 1-3C alkyl group;m = 0-2;X = phenyl group, and -SO3M group has bonded with phenyl group (45 mol% or more);M = H, sodium, lithium, potassium or ammonium;andn = 1 or 2.Initially, hydrolysis and polycondensation reaction of silanized compound (A) are advanced by adding water to compound (A).Hydrolysis and polycondensation reaction of silanized compound (A) are further advanced by adding and mixing water, silanized compound (B) and organic polymer having phenyl group.Silanized compound (B) is further added to the reaction mixture in the middle of the reaction, and is subjected to hydrolysis and polycondensation reaction simultaneously to obtain the gel or sol.Preferred Composition: The ionic conductive material uses organic polymer (in weight parts) (1-6) and silanized compound (B) (2-10) with respect to silanized compound (A) (10). EXAMPLE - Tetra ethoxy silane (in weight parts) (28), methanol, nitric acid (0.04 mol/L) (0.23) and water were mixed in molar ratio of 1:8.5:0.01:1 respectively, and the mixture was stirred at room temperature for 1 hour, and tetra ethoxy silane was hydrolyzed to obtain homogeneous oligomer solution. Subsequently, phenyl triethoxy silane (12) and methanol were added to the homogeneous oligomer solution, and the contents were stirred. Sodium styrene sulfonate (having mean molecular weight of 14000)-2-hydroxy ethyl methacrylate copolymer (7.3), and water were added to the stirred contents, and the contents were further stirred for 1 hour to obtain homogeneous sol. The sol was reacted at 40 degrees C for 8 hours to obtain high viscosity sol. A molded product in the form of a rod was formed using the high viscosity sol. The rod-form molded product was heated at more than 100 degrees C for 8 hours to obtain ionic conductive material. The ionic conductive material had high electrical conductivity. The ion exchange molecule of the ionic conductive material had orientation degree of 0.123 in normal-line direction.
