Abstract
Various embodiments disclosed relate to methods of separating a volatile siloxane from a liquid mixture. In various embodiments, the method includes contacting a first side of a first hydrophobic membrane with a liquid feed mixture including a polymer and at least one volatile siloxane. The method can also include contacting a second side of the membrane with a sweep medium including at least one of a sweep gas, a sweep liquid, and a vacuum, to produce a permeate mixture on the second side of the membrane and a retentate mixture on the first side of the membrane, wherein the permeate mixture is enriched in the volatile siloxane, and the retentate mixture is depleted in the volatile siloxane.
