Abstract:
1. A method for producing a hybrid silica polymer composition comprising heating a mixture of 3 -mercaptopropyltrialkoxylsilane, surfactant, water, and base or acid for reaction at 25 to 180°C., thereby providing a hybrid thiol group-containing silica polymer, and oxidizing the hybrid thiol group-containing silica polymer with a peroxide, thereby providing a hybrid silica polymer which is composed of hybrid silica polymer that includes at least one of a thiol group and a sulfonic group, wherein the hybrid silica polymer is represented by a formula (1) and accounts for more than 90 wt % of the hybrid silica polymer composition: where n ranges from 0.03 to less than 1, wherein the base or acid is ammonium hydroxide.
