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.

Use of bis-semiesters of sulfosuccinic acid with polyether diols based

An aqueous concentrate of a tenside of the sulfate and sulfonate type containing at least about 20% by weight of a water-soluble salt of at least one anionic tenside selected from the group consisting of alkyl polyalkylene ether glycol sulfates, alkaryl polyalkylene ether glycol sulfates, alkyl polyalkylene ether glycol sulfosuccinates, alkaryl polyalkylene ether glycol sulfosuccinates, alkyl sulfates, alkaryl sulfonates and alkyl sulfosuccinates and a viscosity reducing amount of a water-soluble salt of a polyglycol ether sulfate selected from the group consisting of monosulfates of poly-lower alkylene ether glycols having a molecular weight of at least 600, disulfates of poly-lower alkylene ether glycols having a molecular weight of at least 600 and mixtures thereof and from 0 to a viscosity reducing amount of a poly-lower alkylene ether glycol having a molecular weight of at least 1,500; as well as the process of improving the flow behavior of difficultly pourable aqueous concentrates of at least one tenside of the sulfate and sulfonate type comprising employing as a viscosity reducing compound a water-soluble salt of a mono- or disulfate of a poly-lower alkylene ether glycol.

The flow behavior of aqueous surfactant concentrates containing at least 20 wt. % of water-soluble salts of alkylpolyglycolether sulfosuccinates and/or alkylarylpolyglycolether sulfosuccinates is improved by adding to these concentrates at least one of the following viscosity regulators: a lower polyalkyleneether glycol having a molecular weight of at least about 1500; a water-soluble salt of a monosulfosuccinate of a lower polyalkyleneether glycol having a molecular weight of at least about 600; and a water-soluble salt of a disulfosuccinate of a lower polyalkyleneether glycol having a molecular weight of at least about 600.

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.
