Abstract

PURPOSE: To prepare an organosilicon polymer having alkoxy groups and soluble in solvents, by reacting silicic acid with an organosilicon compound in a hydrous solvent, and by treating the resultant organosilicon polymer having partial residual silanol groups, with an alcohol.
CONSTITUTION: (A) Silicic acid is reacted with (B) an organosilicon compound having halogen atoms or alkoxy groups (e.g. formulas I and/or II (R is hydrocarbon group or carbon-functional organic group; X is halogen or alkoxy; n is integer 1W3; m is 3 or 4)] in a hydrous solvent, e.g. hydrous alcohols, etc., to give an organosilicon polymer having partial residual silanol groups. The polymer is brought into contact with an alcohol, e.g. n-butyl alcohol, to give the desired polymer.
