Highly Stable Poly(m-carboranyl-siloxane) Elastomers: Synthesis, Characterisation and Thermal/Radiation stability

摘要

Poly(siloxane) materials incorporating an icosahedral C2B_(10)H_(10) carborane, unit in their main chain and have demonstrated useful properties under extreme conditions[1]. The carborane cage can be envisaged as a nano-scale internal modifier aiding engineering and mechanical properties whilst improving thermal stability without the problems associated with a polymer/filler/water interface. The elastomer network can be readily probed using solid state NMR techniques thereby providing an insight into dynamic time scales that can reflect viscoelastic properties[2].
