| description | A method for purifying a reclaimed polypropylene is disclosed. In one embodiment, the method involves obtaining reclaimed polypropylene, contacting the reclaimed polypropylene with a first fluid solvent to produce an extracted reclaimed polypropylene; then dissolving the extracted reclaimed polypropylene in a solvent to produce a first solution comprising polypropylene. The first solution is settled and then filtered. A purer polypropylene is separated from the resulting solution. |
