  • Patent number: 10795058
    Abstract: A hydrophilic siloxane copolymer of siloxane and hydrophilic organic monomer/s The copolymers can be functionalized to make them capable of undergoing further polymerization by thermal or actinic radiations. The hydrophilicity of these polymers can be varied by varying the siloxane versus organic monomer ratio thereby going from water dispersible to soluble states. The siloxane content can be tuned accordingly in order to provide moderate to high oxygen permeability. These copolymers can be used as a single component curable composition which results in hydrogels to minimize the presence of leachable components thus by reducing the processing cost. The polymers may also find applications in personal care formulations as copolymers, film-formers, hydrogels, coating, emulsions/latex etc.

  • Patent number: 10781289
    Abstract: A method includes the steps of (a) adding an organosilicon compound containing methyl groups and a surfactant into water, mixing well and carrying out hydrolysis to get a mixed aqueous solution; (b) mixing the mixed aqueous solution with 0.1-0.2M ammonium hydroxide and a remaining percentage of an organic solvent, and stirring the mixture under nitrogen atmosphere for emulsion polymerization to get a water-in-oil (w/o) emulsion; and (c) removing the organic solvent and drying the w/o emulsion to get aerogel particles. Thereby the aerogel particles are produced by the present method without hydrophobic treatment and solvent exchange. Therefore the cost and time used for preparing the aerogel particles are saved.
