  • Ionically modified silicones, compositions, and medical devices formed therefrom
    Patent number: 11884779
    Abstract: A hydrophilic silicone, compositions comprising the same, and articles comprising the same are shown and described herein. The hydrophilic silicone is an ionically modified silicone compound wherein the compound comprises a zwitterionic moiety and has a net neutral charge. The hydrophilic silicone compounds may be provided as part of a composition, e.g., a composition suitable for forming a hydrogel, which may be employed to form a film material and even an article (e.g., in a contact lens).

  • PROCESS FOR SYNTHESIS OF ORGANOSILICON COMPOUNDS FROM HALOSILANES
    Publication number: 20230312617
    Abstract: A process for synthesis of an organosilicon compound is provided herein. Also, novel organosilicon compounds prepared by the present process is provided herein. The process comprises the reaction of a halosilane with an organofunctional alkyl halide in the presence of a metal catalyst, a promoter, and an optional co-catalyst. The process provides an efficient synthetic route to produce organosilicon compounds. The process also allows synthesis of organosilicon compounds with a plurality of different functional groups.
