    • A composition includes a siloxane of the formula: (RMe2Si01/2)a(MeRSi02/2)b(RSi03/2)o(Si04/2)d wherein a is at least 2, b is from 3 to 20, c is from 0 to 10, d is from 0 to 10, and each R is independently of the formula -CR'2-CR'2-Y-Z or -CRVCRVZ, wherein each R1 is independently a hydrogen atom or a Ci to C1O hydrocarbyl free of aliphatic unsaturation so long as at least one R' is a hydrogen atom, Y is a divalent organic group, and Z is a polycyclic group containing at least one aromatic ring.. A method of making the siloxane includes charging (HMe2SiO i/2)a(MeHSi?2/2)b(HSi?3/2)c(Si?4/2)d, a platinum catalyst, and an alkene of the formula CR2=CR-Y-Z or CR2=CR-Z into a reactor to form the siloxane. The siloxane is useful as a component in holographic storage media for photopolymer-based holographic data storage applications. The siloxane exhibits excellent compatibility when mixed with a polymerizable component before the polymerizable component is cured. Furthermore, the siloxane exhibits excellent diffusion from polymers of the polymerizable component after partial and complete curing. The siloxane also has a high refractive index while maintaining the excellent compatibility and diffusion properties when mixed with polymerizable component.

    • The present invention encompasses, in part, a method and apparatus for lens casting in which two molds (20 and 40), preferably formed of plastic, are interconnected or joined together via a ring (50) to form a mold cavity (60) having substantially the same dimensions of the lens to be formed therein. The invention is further directed to compositions and methods used in lens casting. In a first implementation the invention includes a mold (10) having a ring (50) having an interior periphery (54), a front mold (20) formed of a plastic and having a lens-forming surface (22), an edge (28) circumscribing the lens-forming surface that is sized to be complementarily received within a portion of the interior periphery of the ring, and a base (30) having dimensions greater than the interior periphery, and a rear mold (40) formed of a plastic having a lens-forming surface (42).
