Abstract: A method for reducing an amount of a contaminant in a thermoplastic polymer comprising shearing a combination comprising a contaminated thermoplastic polymer in melt form, water, and a dispersing agent where the shearing causes a portion of the contaminant to be removed from the contaminated thermoplastic polymer (e.g. moved into an aqueous phase with the water or into another separate phase from the water and the polymer), and after shearing, separating the thermoplastic from the aqueous phase to recover thermoplastic polymer.

Abstract: A coating composition which comprises a dispersion which is a melt blended product of one or more olefinic base polymers; one or more dispersants; one or more compatibilizers; water; and optionally base; wherein the dispersion exhibits an average volume mean particle size diameter of less than or equal to 2 microns, a solids content of equal to or less than 70 wt %, and a pH of 8 or greater; one or more rheology modifiers; and optionally one or more neutralizing agents is provided. An article coated with the coating composition and a method of making the coated article are also provided.
