    摘要: Disclosed is a translucent prespotting composition containing a single phase liquid microemulsion at the processing temperature. The single phase microemulsion comprises a gelling agent, one or more surfactants, a water immiscible solvent or a mixture of water immiscible solvents which may contain no more than about 2 weight percent water at 25.degree. C. when the organic solvent is saturated with water in absence of surfactants or other additives, and water in amounts greater than about 15 percent by weight and less than about 60 percent by weight of the composition. The microemulsions before gelling or solidifying may be oil continuous, water continuous, or bicontinous.

    摘要: The present invention refers to a high internal phase polyclectrolyte emulsions which are useful for the manufacture of superabsorbent polymers having two phases: i) a continuous oil phase and the ii) a dispersed aqueous phase containing the aqueous monomer solution prior to polymerization and the polyelectrolyte in water-soluble, or water-swellable or very slightly crosslinked form after polymerization, wherein the polymerization occurs in the dispersed aqueous phase and wherein the dispersed aqueous phase contains a high concentration of polyclectrolyte. The present invention also refers to a process for preparing such emulsions and for inverting these emulsions so as to form films or other patterns of the superabsorbent polymer. Absorbent structures containing SAP films or other patterns prepared by the present invention are also contemplated.

    摘要: A process for hypochlorinating unsaturated alpha-olefins to produce chlorohydrins which comprises forming a microemulsion of water and an unsaturated alpha-olefin and then adding an oxidant to the microemulsion under conditions sufficient to form the chlorohydrins. The microemulsion is formed by adding a non-nucleophilic surfactant and, optionally, a co-surfactant, to the mixture of water and unsaturated alpha-olefin.
