ABSTRACT:
An improved method for preparing aqueous dispersions of metal soaps in the presence of an ionic surfactant formed in-situ is described. The method comprises two main steps: (a) partially neutralizing a saturated or unsaturated fatty acid containing between 8 to 28 carbon atoms with an alkali metal oxide or hydroxide including ammonia and (b) mixing the resulted dispersion with an aqueous dispersion of a metal oxide or hydroxide, said metal being selected from calcium, magnesium, calcined calcium carbonate, calcined dolomite, strontium, barium and any mixture thereof. The preferred alkali metal used in step (a) is selected from lithium, sodium, potassium and any mixture thereof. The fatty acid used in step (a) is selected from stearic acid, palmitic acid, myristic acid, oleic acid, linoleic acid and any mixture thereof. The concentration of the aqueous dispersion of metal soaps is generally in the range of between 0.2% to 50% by weight. The aqueous dispersions of metal soaps were found to be useful as additives for improving the flowability of polymer materials.
