Abstract
[ 42557‐10‐8 ] C 2 H 6 OSi n (MW 74.02) InChI = 1S/C2H6OSi/c1‐4(2)3/h1‐2H3 InChIKey = SEUDSDUUJXTXSV‐UHFFFAOYSA‐N Alternate names: PDMS; dimethicone; polymerized siloxane; silicone; Sylgard 184; trimethylsiloxy‐terminated polydimethylsiloxane. Physical Data: colorless free‐flowing liquid; average molecular weight is supplier dependent; d 0.98 g mL −1 Solubility: most chlorinated, hydrocarbon, or ethereal solvents. Insoluble in MeOH, EtOH, glycerol, and water. Limited solubility in DMF and DMSO. Form Supplied in: PDMS thimbles are fabricated from commercially available Sylgard 184 – a two‐component prepolymer of PDMS. Typical impurities include residual Pt catalyst. This polymer has a high concentration of silica nanoparticles. Preparative Methods: reaction between dimethylchlorosiloxane and water yields PDMS. The anionic polymerization of hexamethylcyclotrisiloxane yields PDMS. PDMS thimbles are fabricated by curing Sylgard 184 in an oven. Handling, Storage, and Precautions: PDMS thimbles may be stored for over a year under ambient conditions. No specific precautions are necessary.
