A new microporous polysiloxane solid particle containing hydroxyl (POS-OH) was prepared, and the synthesis method was simple. A certain amount of methyldiethoxysilane (containing triethoxysilane) and allyl alcohol were heated at 90℃ in oil bath for 20h with using platinum compound as catalyst, and OSI-OH was prepared by hydrosilation addition reaction. Then the POS-OH was synthesized by hydrolysis condensation reaction with using OSI-OH in sulfuric acid aqueous solution (containing 40% sulfuric acid) at 35℃ for 1h. The yield was 92.77%. The structure of POS-OH was characterized by FTIR, SEM, TGA, XRD and 29Si-NMR. And through analysis, it was proved that the product was a new kind of polysiloxane
