Abstract:
A method for purifying a reclaimed polymer is disclosed. In one embodiment, the method involves obtaining reclaimed polymer, contacting the reclaimed polymer 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. The first solution is settled and then filtered. A purer polymer is separated from the resulting solution.
