  • PREPARATION OF IMINE-FUNCTIONAL ORGANOSILICON COMPOUNDS AND PRIMARY AMINO-FUNCTIONAL ORGANOSILICON COMPOUNDS
    Publication number: 20240368200
    Abstract: An organosilicon compound with a primary amino-functional group is prepared. A catalyzed reductive amination process for combining a secondary imine-functional organosilicon compound with ammonia and hydrogen produces the primary amino-functional organosilicon compound.
    Type: Application
    Filed: October 6, 2022
    Publication date: November 7, 2024
    Inventors: Erich Molitor, Joseph Neuman, Michael Tulchinsky, Ruth Figueroa, Jason Fisk, David Devore, Mrunmayi Kumbhalkar, Michael Ferritto, Michael Telgenhoff, Brian Rekken
  • PREPARATION OF PROPYLIMINE-FUNCTIONAL ORGANOSILICON COMPOUNDS AND PRIMARY AMINOPROPYL-FUNCTIONAL ORGANOSILICON COMPOUNDS
    Publication number: 20240279255
    Abstract: An organosilicon compound with a primary aminopropyl-functional group is prepared. A catalyzed reductive amination process for combining a secondary propylimine-functional organosilicon compound with ammonia and hydrogen produces the primary aminopropyl-functional organosilicon compound.
    Type: Application
    Filed: October 6, 2022
    Publication date: August 22, 2024
    Inventors: Erich Molitor, Joseph Neuman, Michael Tulchinsky, Ruth Figueroa, David Devore, Mrunmayi Kumbhalkar, Michael Ferritto, Michael Telgenhoff, Brian Rekken, Souvagya Biswas, Michael A. Brammer, Heather A. Spinney
  • AMINOSILOXANE ESTER COPOLYMER AND METHODS FOR THE PREPARATION AND USE OF THE COPOLYMER
    Publication number: 20240180813
    Abstract: An aminosiloxane ester copolymer, an emulsion containing the copolymer, and processes for making the copolymer and the emulsion are provided. The copolymer and the emulsion may be formulated into hair care compositions, such as conditioners and styling products.
    Type: Application
    Filed: May 31, 2022
    Publication date: June 6, 2024
    Inventors: Brian Rekken, Nisaraporn Suthiwangcharoen, Anirudha Banerjee, Zachary Wenzlick, Dawn Carsten, Qian Feng, Kimmai Nguyen
  • PROCESSES FOR MAKING POLYSILOXAZANES AND USING SAME FOR PRODUCING AMINO-FUNCTIONAL POLYORGANOSILOXANES
    Publication number: 20240124653
    Abstract: A process for preparing a cyclic polysiloxazane is disclosed. The cyclic siloxazane may optionally be converted to an ?-alkoxy-?-amino-functional polysiloxane. The cyclic siloxazane or the ?-alkoxy-?-amino-functional polysiloxane, may be used as a capping agent for a silanol-functional polyorganosiloxane in a process to make an amino-functional polyorganosiloxane.
    Type: Application

  • Processes for making polysiloxazanes and using same for producing amino-functional polyorganosiloxanes
    Patent number: 11760839
    Abstract: A process for preparing a cyclic polysiloxazane is disclosed. The cyclic polysiloxazane may optionally be converted to an a-alkoxy-ou-amino-functional polysiloxane. The cyclic polysiloxazane or the a-alkoxy-oo-amino-functional polysiloxane, may be used as a capping agent for a silanol-functional polyorganosiloxane in a process to make an amino-functional polyorganosiloxane.
    Type: Grant
