  • Method for separating and purifying polymers from reclaimed product
    Patent number: 11001693
    Abstract: A method for separating and purifying polymers of a reclaimed product (rP) is disclosed. The rP is contacted at an elevated temperature and pressure, with an extraction solvent to produce an extracted rP (erP). A solvent, at conditions sufficient to solubilize the first polymer, contacts the erP to produce a solution, which is purified at an elevated temperature and pressure by contacting it with a solid medium to produce a purified solution of the first polymer. The purified polymer is then separated from the purified solution, and the method steps are repeated until all polymers are separated and purified.
