Supercritical COextraction can therefore be used to produce a silicone oil with, for example, an index of refraction substantially the same as a bulk polymer to be used in an intraocular lens (e.g., in a fluid-driven accommodating intraocular lens). Because supercritical extraction conditions can be varied to get separation based on chemical affinity, this purification method can also be used to achieve a desired refractive index. This class of polymerization reactions can be used to prepare polymers with a variety of 1) architectures—including linear, “star”, and “comb” polymers; 2) compositions—homopolymers, random copolymers, block copolymers, and graft copolymers; and 3) functionalized polymers—one and two end functional polymers, and side functional polymers. The absence of side reactions allows living polymerizations to be used to synthesize a variety of materials that would be otherwise difficult to prepare. More recently, radical living polymerizations may have been developed.

In an example of an anionic synthetic route, the use of alkyl lithium compounds in the ring opening polymerization of cyclotrisiloxanes appears to be a “living” polymerization, allowing for the degree of control needed to make the silicone oils described above.

Fractional precipitation of the silicone oil may also be used to separate components of the product polymer.
