PROBLEM TO BE SOLVED: To provide a silica composition which can improve the dispersibility and processability of silica with respect to diene rubber as compared with conventional levels.SOLUTION: A silica composition comprises a complex of silica 100 pts.wt. and hydrogen-bonding surfactant 1-100 pts.wt. The silica composition can be produced by mixing silica 100 pts.wt. and hydrogen-bonding surfactant 1-100 pts.wt. in a banbury mixer.SELECTED DRAWING: None |
