Silsesquioxanes are colorless solids that adopt cage-like or polymeric structures with Si-O-Si linkages and tetrahedral Si vertices. Silsesquioxanes are members of polyoctahedral silsesquioxanes ("POSS"), which have attracted attention as precursors to ceramic materials and nanocomposites. Diverse substituents (R) can be attached to the Si centers. The molecules are unusual because they feature an inorganic silicate core and an organic exterior. The silica core confers rigidity and thermal stability. Vinyl POSS CAS: 69655-76-1 is one of silsesquioxane, attaching 8 vinyl group on its molecular sphere so that its properties and applications would be modified by reaction with other functionalized building blocks. Vinyl POSS is white powder with molecular formula (C16H24O12Si8).
