A method for purifying a reclaimed polypropylene comprising: a. obtaining the reclaimed polypropylene wherein the reclaimed polypropylene is selected from the group consisting of post-consumer use polymers, post-industrial use polymers, and combinations thereof; b. contacting the reclaimed polypropylene at a temperature from 80°C to 280°C and at a pressure from 150 psig (1.03 MPa) to 8,000 psig (55.16 MPa) with a first fluid solvent having a standard boiling point less than 70°C, to produce an extracted reclaimed polypropylene; c. dissolving the extracted reclaimed polypropylene in a solvent selected from the group consisting of the first fluid solvent, a second fluid solvent, and mixtures thereof, at a temperature from 90°C to 280°C and a pressure from 200 psig (1.38 MPa) to 8,000 psig (55.16 MPa) to produce a first solution comprising polypropylene, at least one dissolved contaminant, and at least one suspended contaminant, wherein the reclaimed polypropylene is dissolved in the fluid solvent, or fluid solvent mixture, at a mass percent concentration of at least 0.5%; d. settling the first solution comprising polypropylene, at least one dissolved contaminants, and at least one suspended contaminant at a temperature from 90°C to 280°C and at a pressure from 200 psig (1.38 MPa) to 8,000 psig (55.16 MPa) to produce a second solution comprising polypropylene, at least one dissolved contaminant, and less of the at least one suspended contaminant; e. filtering the second solution at a temperature from about 90°C to 280°C and at a pressure from 200 psig (1.38 MPa) to 8,000 psig (55.16 MPa) to produce a third solution comprising purer polypropylene, at least one dissolved contaminant, and even less of the at least one suspended contaminant; and f. separating the purer polypropylene from the third solution; and wherein the second fluid solvent has the same chemical composition or a different chemical composition as the first fluid solvent. a. obtaining the reclaimed polypropylene wherein the reclaimed polypropylene is selected from the group consisting of post-consumer use polymers, post-industrial use polymers, and combinations thereof; b. contacting the reclaimed polypropylene at a temperature from 80°C to 280°C and at a pressure from 150 psig (1.03 MPa) to 8,000 psig (55.16 MPa) with a first fluid solvent having a standard boiling point less than 70°C, to produce an extracted reclaimed polypropylene; c. dissolving the extracted reclaimed polypropylene in a solvent selected from the group consisting of the first fluid solvent, a second fluid solvent, and mixtures thereof, at a temperature from 90°C to 280°C and a pressure from 200 psig (1.38 MPa) to 8,000 psig (55.16 MPa) to produce a first solution comprising polypropylene, at least one dissolved contaminant, and at least one suspended contaminant, wherein the reclaimed polypropylene is dissolved in the fluid solvent, or fluid solvent mixture, at a mass percent concentration of at least 0.5%; d. settling the first solution comprising polypropylene, at least one dissolved contaminants, and at least one suspended contaminant at a temperature from 90°C to 280°C and at a pressure from 200 psig (1.38 MPa) to 8,000 psig (55.16 MPa) to produce a second solution comprising polypropylene, at least one dissolved contaminant, and less of the at least one suspended contaminant; e. filtering the second solution at a temperature from about 90°C to 280°C and at a pressure from 200 psig (1.38 MPa) to 8,000 psig (55.16 MPa) to produce a third solution comprising purer polypropylene, at least one dissolved contaminant, and even less of the at least one suspended contaminant; and f. separating the purer polypropylene from the third solution; and wherein the second fluid solvent has the same chemical composition or a different chemical composition as the first fluid solvent.
