[Physical properties]

colorless free-flowing liquid; average molecular weight is supplier dependent; d 0.98 gmL?1
[Uses]

PDMS Thimbles? can be used in Differential Flux of Reagents and Catalysts ThroughPDMS Thimbles. In summary, a wide variety of organic molecules with various functional groups flux throughPDMSthimbles, but care should be taken to consider the solvent, thickness of the walls, temperature, and the presence of any ionic functional group.
[Preparation]

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.
