A modified silicone resins of Formula (II): and an elastomer formulation comprising such a modified silicone resins of Formula (II) are presented. The R 6 , R 7 , R 8 , R 9 , R 10 , R 11 , R 12 and R 13 are each independently selected from a group consisting of H, alkyl, alkenyl, alkynyl, and aryl. The X is selected from a group consisting of arylene, transition metal, inorganic oxide, silsesquioxane and and wherein R 55 and R 56 are independently selected from a group consisting of methyl or phenyl. The values of t ranges from 1 to 10, y ranges from 1 to 200 and z ranges from 1 to 1,000. The elastomeric materials prepared from modified silicone resins display robust mechanical properties following prolonged exposure to high temperatures (e.g., 316°C or higher).
