Summary:The invention relates to a preparation method of polyhydroxy modified octavinyl cage silsesquioxane, and belongs to the technical field of preparation of silsesquioxane. The method comprises the following steps: weighing octavinyl cage silsesquioxane and methallyl alcohol according to the molar ratio of 1:8-15; dissolving the octavinyl cage silsesquioxane and azobisisobutyronitrile in tetrahydrofuran, and dropwise adding the methallyl alcohol; reacting the obtained mixed solution under the condition of ultraviolet light under the condition of stirring; performing rotary evaporation and concentration on the obtained product to obtain transparent viscous liquid, and drying in a 50 DEG C oven for 12 hours to obtain the polyhydroxy modified octavinyl cage silsesquioxane. The preparation methodhas the advantages that the industrial octavinyl cage silsesquioxane is used as a raw material, the polyhydroxy modified octavinyl cage silsesquioxane is obtained through catalytic reaction, the rawmaterial source is wide, t
