Abstract
PURPOSE: To prepare easily an organosilicon polymer soluble in organic solvents and having improved film-formability in a high yield in a simplified process, by reacting an organosilicon compound with silicic acid heat-treated in water and/or a polar solvent.
CONSTITUTION: Silicic acid is heat-treated in water and/or a polar solvent, e.g. alcohols, under acidic conditions of pH0.4W3.5 at 30°C to the boiling point of the solvent. One mole of the treated silicic acid (A) is reacted with preferably 0.7W 2.0 moles of an organosilicon compound (B) having halogen atoms or alkoxy groups [pref. formula I or II (R is hydrocarbon group or carbon-functional organic group; X is halogen or alkoxy group; n is integer 1W3; m is 3 or 4)] preferably at 20°C to the boiling point of the solvent to give the desired polymer.
