  • Process for increasing the viscosity of aqueous solutions of homogeneous copolymers of vinyl pyrrolidone and n-3, 3-dimethylaminopropyl methacrylamide
    Patent number: 5844041
    Abstract: A process is described for increasing the viscosity and high humidity curl retention of aqueous solutions of homogeneous copolymers of 20-99% vinyl pyrrolidone (VP) and 1-80% N-3,3-dimethylamino-propyl methacrylamide (DMAPMA). The high viscosity solutions are particularly useful as the active component of hair care products.

  • Pentafluorosulfur hypochlorite
    Patent number: 3956470
    Abstract: Pentafluorosulfur hypochlorite, SF.sub.5 OCl, and its preparation by reacting thionyl tetrafluoride, SOF.sub.4, or a salt thereof, with an inorganic reagent containing a chlorine atom in a +1 oxidation state which chlorine atom is attached to a more electronegative element. When SOF.sub.4 is employed, it is necessary to use a catalyst for the reaction selected from the group consisting of LiF, NaF, KF, RbF and CsF. Pentafluorosulfur hypochlorite is useful as a polymerization initiator and is a valuable intermediate for the synthesis of other useful compounds.
