  • Composition including a siloxane and a method of forming the same
    Patent number: 8222364
    Abstract: A composition includes a siloxane of the formula: (RMe2SiO1/2)a(MeRSiO2/2)b(RSiO3/2)c(SiO4/2)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 CR?2—CR?2—Z, wherein each R? is independently a hydrogen atom or a C1 to C10 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 (HMe2SiO1/2)a(MeHSiO2/2)b(HSiO3/2)c(SiO4/2)d, a platinum catalyst, and an alkene of the formula CR?2?CR?—Y—Z or CR?2?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.

  • Composition Including A Siloxane And A Method Of Forming A The Same
    Publication number: 20100105844
    Abstract: 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.

  • Cross-linked organopolysiloxanes and emulsions based thereon
    Patent number: 5136068
    Abstract: The specification discloses an organopolysiloxane-polyoxyalkylene emulsifier for polar in nonpolar liquid emulsions wherein organopolysiloxane-polyoxyalkylene polymer molecules are intentionally cross linked through a cross linking agent joined thereto by nonhydrolyzable bonds and being free of internal hydrolyzable bonds.
