Siloxane bond partial ionic nature

Siloxane Bond Energy and Partially Ionic Character, Low intermo-lecular forces and high chain flexibility explain most of the physical behavior of PD MS in various environments. The hybrid organic-inorganic nature of PD MS has chemical consequences that are primarily due to two other key properties of the siloxane backbone its high bond energy and partially ionic character. For instance, these properties are clearly responsible for the substantial thermal stability of silicones.
