摘要： 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.
摘要翻译：组合物包括下式的硅氧烷：（RMe2Si01 / 2）a（MeRSi02 / 2）b（RSi03 / 2）o（Si04 / 2）d其中a为至少2，b为3至20，c为 0至10，d为0至10，并且每个R独立于式-CR'2-CR'2-YZ或-CRVCRVZ，其中每个R 1独立地为氢原子或不含脂族的C 1至C 10烃基只要至少一个R'为氢原子，Y为二价有机基团，Z为含有至少一个芳环的多环基团，则不饱和键。制备硅氧烷的方法包括将（HMe 2 SiO 1/2）（MeHSi 2/2）b（HSi 3/2）c（Si 4/2）d，铂催化剂和式CR2 = CR-YZ或CR2 = CR-Z的烯进入反应器形成硅氧烷。硅氧烷可用作用于基于光聚合物的全息数据存储应用的全息存储介质中的组分。当可聚合组分固化之前，与可聚合组分混合时，硅氧烷显示出优异的相容性。此外，部分和完全固化后，硅氧烷表现出可聚合组分的聚合物的极好扩散。当与可聚合组分混合时，硅氧烷还具有高折射率，同时保持优异的相容性和扩散性。
