Patent number: 11008433Abstract: 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.Type: GrantFiled: May 28, 2019Date of Patent: May 18, 2021Assignee: The Procter & Gamble CompanyInventors: John Moncrief Layman, Dimitris Ioannis Collias, Hans Schonemann, Kara Williams

Patent number: 10961366Abstract: A method for purifying a reclaimed polymer is disclosed. In one embodiment, the method involves obtaining reclaimed polymer, contacting the reclaimed polymer with a first fluid solvent to produce an extracted reclaimed polymer; then dissolving the extracted reclaimed polymer in a solvent to produce a first solution comprising polymer. The first solution is settled and then filtered. A purer polymer is separated from the resulting solution.Type: GrantFiled: May 28, 2019Date of Patent: March 30, 2021Assignee: The Procter & Gamble CompanyInventors: John Moncrief Layman, Dimitris Ioannis Collias, Hans Schonemann, Kara Williams
