  • Organo-modified silicone polymers
    Patent number: 9944742
    Abstract: A linear silicone polymer suitable for use in producing homopolymers, copolymers, polymerized emulsions, latex compositions, and hydrogel polymer films. In one aspect, a hydrophilic silicone monomer is of the Formula 1: WAmBnW??(1) Where, A is a divalent block comprising a silicone-containing pendant group. In one embodiment, the silicone-containing pendant group comprises polyalkylene oxide groups. The structure of the polymer can be controlled and tuned to provide a material with excellent wettability and oxygen permeability. The polymers are suitable for use in a variety of applications including in providing a film for forming contact lenses.
    Type: Grant
    Filed: September 22, 2014
    Date of Patent: April 17, 2018
    Assignee: Momentive Performance Materials Inc.
