Abstract: A method for purifying a reclaimed polymer, such as a polymer reclaimed from post-consumer use or post-industrial use, is disclosed. The method involves obtaining the reclaimed polymer and contacting it at an elevated temperature and pressure with a fluid solvent to produce an extracted reclaimed polymer. The extracted reclaimed polymer is dissolved in a solvent at an elevated temperature and pressure to produce a polymer solution. A polymer is then separated from the polymer solution.

Abstract: A method for purifying a reclaimed polymer is provided. The method involves obtaining reclaimed polymer, contacting it with a first fluid solvent to produce an extracted reclaimed polymer then dissolving the extracted reclaimed polymer in a solvent to produce a first solution comprising polymer and suspended contaminants. The first solution is settled to produce a second solution comprising polymer and remaining contaminants. The second solution is purified by contacting the second solution with solid media to produce a third solution comprising purer polymer. Finally, the purer polymer is separated from the third solution.
