    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, which is purified at an elevated temperature and pressure by contacting the polymer solution with solid media to produce a purer polymer solution. A purer polymer is then separated from the purer polymer solution.
