    Abstract: This invention provides phyllosilicates and polyfunctional dispersants which can be manipulated to selectively control the viscosity of phyllosilicate slurries. The polyfunctional dispersants used in the present invention, which include at least three functional groups, increase the dispersion and exfoliation of phyllosilicates in polymers and, when used in conjunction with phyllosilicate slurries, significantly reduce the viscosity of slurries having high concentrations of phyllosilicates. The functional groups of the polyfunctional dispersants are capable of associating with multivalent metal cations and low molecular weight organic polymers, which can be manipulated to substantially increase or decrease the viscosity of the slurry in a concentration dependent manner. The polyfunctional dispersants of the present invention can also impart desirable properties on the phyllosilicate dispersions including corrosion inhibition and enhanced exfoliation of the phyllosilicate platelets.

    Abstract: A continuous process for manufacture of soap thickened grease compositions where a saponifiable material and a metal base are continuously introduced at an elevated temperature into a saponification zone maintained at superatmospheric pressure and saponified under turbulent conditions, wherein the saponified product is mixed with an aqueous solution of oil-insoluble additive materials at a superatmospheric pressure sufficient for maintaining all water in the liquid phase, wherein the saponified material-additive mixture is heated to an elevated temperature of at least 350.degree. F., wherein the heated saponified material additive mixture is flowed into a dehydration zone maintained at a reduced pressure for flash vaporizing substantially all water therefrom and producing a dehydrated saponified material having oil-insoluble additive evenly dispersed therethrough as particles not exceeding about 10 microns, and wherein the dehydrated saponified material is blended with lubricating oil to produce a grease product.
