    摘要: 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 filtering it and 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.

    摘要: 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. A polymer is then separated from the polymer solution.
