Application
Hexamethylcyclotrisiloxane (D3) can be used in the synthesis of:
- Polysiloxanes by anionic ring-opening polymerization.
- Thin films by pulsed- plasma-enhanced chemical vapor deposition (PECVD) for the application of insulating biomaterials.
- Dimethoxydimethylsilane by treating with dimethyl carbonate via deoligomerization using alkali metal hydroxide catalyst.
