Temperature-resistant silicone resins

Abstract:

Methods and formulations for modified silicone resins of Formula (I) are presented: ##STR00001## The R.sup.1, R.sup.2, and R.sup.3 are each independently selected from a group consisting of H, alkyl, alkenyl, alkynyl, and aryl; n ranges from 1 to 10; m ranges from 1 to 200; and p ranges from 2 to 1,000. The elastomeric materials prepared from modified silicone resins display robust mechanical properties following prolonged exposure to high temperatures (e.g., 316.degree. C. or higher).
