TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Compound: The metallic compound has formula: MXn1(OH)n2R1n3(OR2)n4.X = halogen atom or isocyanate group;M = metal atom, preferably silicon, titanium, boron and aluminum;R1 = 1-5C alkyl group optionally having substituent;R2 = 1-5C alkyl group optionally having substituent or 2-11C acyl group optionally having substituent;n1-n4 = 0 or 1-m;m = valence of M; andn1+n2+n3+n4 = m.    TECHNOLOGY FOCUS - POLYMERS - Preferred Method: The organic polymer and metallic compound are heat-processed, and a condensate containing reactive group of one portion of metallic compound or its condensate, and organic polymer is obtained.Preferred Composition: The molar ratio of organic polymer and metallic compound having reactive groups, is 0.7-1.5:1.Preferred Polymer: The organic polymer has repeating unit of formula (II).R3 and R4 = 1-8C hydrocarbon group optionally having substituent and H; andn = 2-6, preferably 2. EXAMPLE - Tetramethoxy silane (in g) (1.52) and polyethylene glycol of formula (II) (4) were added at room temperature, and stirred at 80degreesC for 24 hours under nitrogen atmosphere. A composite of organic polymer and silicon compound was obtained. The reaction product was analyzed using spectrum, and 1.5 pieces of methyl group of tetra methoxy silane were found to be substituted by polyethylene glycol. Distilled water (0.36) was added at room temperature, stirred at 80degreesC for 6 hours, and hydrolysis-condensation was performed. Lithium perchlorate (0.48) and acetonitrile (2 ml) were further added under argon atmosphere, to obtain a solution. The obtained solution was casted on an aluminum board having thickness of 0.3 mm, dried at 120degreesC for 3 hours, and the produced cast film was peeled from the board. A transparent thin film having thickness of 120 micronsm was obtained. The obtained film had electrical conductivity of 1.5x10-4 S/cm at 30degreesC, 2x10-4 S/cm at 40degreesC and 2.5x10-4 S/cm at 50degreesC.    n = 4.1.
