METHOD FOR PURIFYING CONTAMINATED POLYMERS |
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 dissolving it in a solvent at an elevated temperature and pressure to produce a polymer solution, which is purified at an elevated temperature and pressure by contacting the polymer solution with solid media to produce a purer polymer solution. A purer polymer is then separated from the purer polymer solution. |
