  • Method of preparing microemulsions of amino silicone fluids and MQ resin mixtures
    Patent number: 6180117
    Abstract: Microemulsion compositions comprising MQ resins and microemulsifiable amino silicone fluids or gums and a surfactant having a high phase inversion temperature, the microemulsions formed therewith, a means for preparing said microemulsions, and personal care products comprising said microemulsions.
    Type: Grant
    Filed: February 10, 1995
    Date of Patent: January 30, 2001

  • Process for preparing hydrogen siloxane copolymers
    Patent number: 5965683
    Abstract: A sequential catalysis of the ring opening polymerization of cyclic organosiloxanes using a base catalyst that can be neutralized by a subsequent redistribution and condensation catalyst such as a Lewis acid catalyst, preferably a phosphonitrilic compound, permits the rapid synthesis of functionalized and poly-functionalized silicone copolymers such as alkenyl hydride copolymers, a new composition of matter. The instant claims are drawn to branched siloxanes having both Si--H and Si-alkenyl groups.
