Title: Silsesquioxane resin with high strength and fracture toughness and method for the preparation thereof

Abstract: A cured silsesquioxane resin and method for its preparation are disclosed. By using a silyl-terminated hydrocarbon in the hydrosilylation reaction curable composition used to prepare the cured silsesquioxane resin, the cured silsesquioxane resin has improved strength and toughness without significant loss of modulus. A typical silyl-terminated hydrocarbon useful in this invention is silphenylene.
