Patent number: 10463737Abstract: Silicone acrylate copolymer composition, namely, silicone resin-acrylate copolymers and methods of preparing the same. The silicone acrylate composition may include a silicone resin coupled with an acrylate polymer via a linking group. The silicone acrylate composition may be formed by preparing an acrylate or a (meth)acrylate functional resin and carrying out acrylate polymerization in the presence of a functionalized resin. A silane-functional acrylate polymer may be prepared, followed by a reaction to couple a resin to the silane-functional acrylate polymer. The resulting copolymer may then be used as desired, e.g., added to a silicone and acrylate mixture to create a non-separating blend.Type: GrantFiled: January 29, 2016Date of Patent: November 5, 2019Assignee: DOW CORNING CORPORATIONInventors: Robert O Huber, Gary Lee Loubert, Gerald K Schalau, II, Simon Toth

Patent number: 10316228Abstract: A multi-phase silicone acrylic hybrid visco-elastic composition prepared by polymerizing an ethylenically unsaturated monomer and a silicon-containing pressure sensitive adhesive composition comprising acrylate or methacrylate functionality in a first solvent in the presence of an initiator, removing the first solvent, and adding a second solvent to form the multi-phase silicone acrylic hybrid visco-elastic composition. Alternatively, a multi-phase silicone acrylic hybrid visco-elastic composition prepared by polymerizing an ethylenically unsaturated monomer and a silicon-containing pressure sensitive adhesive composition comprising acrylate or methacrylate functionality in a first solvent in the presence of an initiator, adding a processing solvent having a higher boiling point than the first solvent, applying heat to selectively remove a majority of the first solvent, removing the processing solvent, and adding a second solvent to form the multi-phase silicone acrylic hybrid visco-elastic composition.Type: GrantFiled: February 5, 2016Date of Patent: June 11, 2019Assignee: DOW SILICONES CORPORATIONInventors: Chana Wilson Evans, Robert O.

Patent number: 8586669Abstract: Silicone paste compositions are disclosed by combining a silicone organic elastomer gel with water or a hydrophilic solvent. The silicone paste compositions may further contain a personal or healthcare active. The silicone organic elastomer gel is prepared by reacting in a carrier fluid an organohydrogensiloxane with two polyoxyalkylenes, the first polyoxyalkylene having aliphatic unsaturation at both each molecular termini, and the second polyoxyalkylene having aliphatic unsaturation at one molecular terminal.Type: GrantFiled: January 5, 2010Date of Patent: November 19, 2013Assignee: Dow Corning CorporationInventors: John Joseph Kennan, Kathryn Elizabeth Messner, Isabelle Van Reeth, Robert O.

Patent number: 7939570Abstract: A controlled-release composition for topical application to a substrate includes an oil-in-water emulsion and an active agent incorporated into the oil-in-water emulsion. The oil-in-water emulsion is substantially free of lipophilic solvent and is formed by mechanical inversion of a water-in-oil emulsion. The water-in-oil emulsion includes a silicone component, a surfactant, and water. A method of delivering the active agent to the substrate provides the oil-in-water emulsion and incorporates the active agent into the oil-in-water emulsion for delivery of the active agent to the substrate upon application of the oil-in-water emulsion to the substrate.Type: GrantFiled: October 27, 2004Date of Patent: May 10, 2011Assignee: Dow Corning CorporationInventors: Victor A.
