Hydrosilation routes to materials with high thermal and oxidative stabilities

Poly(cyclosiloxane–carborane)s for harsh environments

“…1(e)) showed a new peak at 1198 cm −1 (Si–C–C stretching), and the intensity of the Si–H stretching (2160 cm −1 ) and C–H stretching (3040 cm −1 ) indicated that hydrosilylation occurred. 24–26 For all samples, the peak at 3040 cm −1 (C–H) disappeared, indicating that the samples were fully cured. However, a small peak at 1630 cm −1 (CC) still remained because of the increasing steric hindrance from highly crosslinked networks.…”

Anomalous behavior of the structural relaxation dispersion function of a carborane-containing siloxane

“…The siloxane VCS was synthesized as previously described [16] and its distilled sample was used as obtained. Dielectric measurements were carried out using a Novocontrol Alpha Analyzer in the frequency range between 10 mHz and 3 MHz.…”

The State of the Art in Boron Polymer Chemistry

“…64) from the reaction of the 1,7-bis(vinyltetramethyldisiloxyl)m-carborane monomer with the polymeric crosslinker, poly(methylhydrosiloxane). 133 The reactions were catalyzed by the Speier's catalyst, H 2 PtCl 6 . Three samples were where Si-Me groups have been substituted either with phenyl or vinyl groups.…”
