Synthesis

There are many synthetic methods for the preparation of POSS, other than the methods used in the first attempts to synthesize this type of compounds. These methods can be divided into three categories. The first is the hydrolysis and condensation of silanes, the second is the preparation of a polyhedron compound from silanols containing less than eight silicon atoms, the third is the modification of the side arms of the already existing polyhedric silsesquioxane or the substitution of a hydrogen atom in octahydrooctasilsesquioxane.
