ABSTRACT:
An organic silicon compound, having high reactivity, represented by the following Formula (1):wherein R and M are defined in the specification. The organic silicon compound is produced by reacting polysilsesquioxane, which is obtained by hydrolyzing a silane compound having three hydrolyzable groups and represented by the following Formula (2), with a monovalent alkaline metal hydroxide in an organic solvent, or by subjecting the silane compound having three hydrolyzable groups to hydrolysis and polycondensation in the presence of an organic solvent and an alkaline metal hydroxide:in-line-formulae description="In-line Formulae" end="lead"?R—Si X3  (2)in-line-formulae description="In-line Formulae" end="tail"?wherein R is the same as in Formula (1) and X represents a hydrolyzable group.
