Abstract: A method for extracting a target polymer from a contaminated polymer compound, including dissolving the contaminated polymer compound using a given solvent, thereby obtaining a dissolved polymer mixture; microfiltering the dissolved polymer mixture to remove non-soluble impurities having a size larger than a size of the target polymer from the dissolved polymer mixture, thereby obtaining a permeate microfiltered polymer solution; and extracting the given solvent from the permeate microfiltered polymer solution, thereby obtaining a feedstock of the target polymer.
