  • Patent number: 4525525
    Abstract: Bis-semiesters of sulfosuccinic acid with polyether diols based on ethylene oxide/propylene oxide and/or their alkali metal and/or ammonium salts as surfactants, i.e., agents for reducing the surface tension of aqueous substrates such as water or aqueous solutions, as dispersants, wetting agents and leveling agents. Another aspect of the invention relates to the use of such bis-semiesters and/or such salts as emulsifiers in the emulsion polymerization of water insoluble monomers.

  • Patent number: 4385183
    Abstract: This invention is directed to the telomerization of water-soluble monomers in an aqueous phase. More particularly, this invention is directed to a process for the telomerization of water-soluble monomers and water-insoluble telogens in aqueous phase, wherein the water-insoluble telogens are solubilized by the addition of an effectively solubilizing amount of surface-active compounds.
