Method for Screening Solvent for Polyvinyl Chloride Extraction, Recycling Method for Waste Material, and Recycled Polyvinyl Chloride and Composition

A method for screening a solvent for extracting polyvinyl chloride (PVC) from waste using the following Equation 1:PVC⁢solubility⁢score=x1⁢exp⁢(-x2⁢μpvcsol-x3⁢μdopsol)+x4⁢exp⁢(-x5⁢rpvc-x6⁢rdop)-x7⁢exp⁢(-x8⁢Vsol)+x9,μij is a chemical potential of the solvent, and in μij, i is a solute and j is the so...

Zusammenfassung:	A method for screening a solvent for extracting polyvinyl chloride (PVC) from waste using the following Equation 1:PVC⁢solubility⁢score=x1⁢exp⁢(-x2⁢μpvcsol-x3⁢μdopsol)+x4⁢exp⁢(-x5⁢rpvc-x6⁢rdop)-x7⁢exp⁢(-x8⁢Vsol)+x9,μij is a chemical potential of the solvent, and in μij, i is a solute and j is the solvent, ri is a Hansen solubility parameter distance of the solvent, Vsol is a molecular volume of the solvent, sol is the solvent, pvc is polyvinyl chloride, and dop is diethylhexyl phthalate. A method for recycling waste is also provided. Additionally, a recycled polyvinyl chloride and a recycled composition are provided.
