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.
