PROBLEM TO BE SOLVED: To obtain the subject composition excellent in storage stability by incorporating therein an alkoxysilylated polysiloxane comprising a specific number or more of a siloxane structure in the molecule and an alcohol of a specific carbon number. SOLUTION: The polysiloxane composition comprises 100 pts.wt. of an alkoxysilylated polysiloxane containing, in the molecule, six or more of a siloxane structure given by the formula and 1-100 pts.wt. of a 1-6C alcohol. 100 pts.wt. of inorganic solid particles of a metallic oxide, or the like, such as silica are treated with 1-50 pts.wt. of the polysiloxane composition to form surface-treated inorganic solid particles. 100 pts.wt. of rubber are blended with 5-100 pts.wt. of the surface-treated inorganic solid particles or with 5-100 pts.wt. of untreated inorganic solid particles and 0.1-30 wt.%, in terms of the alkoxysilylated polysiloxane, of the polysiloxane composition to obtain a composition exhibiting the same performances. In the formula, R1 is methyl, ethyl or phenyl; and R2 is a 1-6C hydrocarbon or ether-linked hydrocarbon. |
