Preparation and Properties of Polyhedral Oligosilsesquioxanes/Polymers Blends

Abstract

The synthesis of silsesquioxane/polymer blends and copolymers has expanded greatly in recent years. These materials have the advantage of combining a well defined ceramic type molecule with an organic polymer which can result in a material that may bridge the performance gap between the two systems. Earlier, we reported that the organic side groups of polyhedral oligosilsesquioxanes (POSS) have an enormous influence on the solubility of POSS in polystyrene with the phenethyl POSS being the most soluble. We now report that phenethyl POSS is dispersible in a wide range of aromatic ring- containing polymers (polycarbonate, SB rubber, etc.) resulting in a clear blend. We also report that aliphatic POSS compounds are also dispersible in high density polyethylene. The synthesis of POSS/polymer blends as well as some physical properties will be discussed.
