Temperature-resistant silicone resins
Methods and formulations for modified silicone resins of Formula (II) are presented. Formula (II) comprises at least one of each of the following subunits:The R1, R2, R3, R6, R7, R8, R9, R10, R11, R12 and R13 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, and silsesquioxane. The values oft 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).
