Recycling method for polyvinyl chloride waste |
| abstract |
(57) [Summary] [Purpose] To recycle highly colored and polluted polyvinyl chloride waste into highly decolorized polyvinyl chloride with high added value. [Structure] A polyvinyl chloride solution obtained by dissolving polyvinyl chloride waste in a predetermined solvent and removing insolubles is supplied to a non-aqueous precipitation medium that is insoluble in the polyvinyl chloride and compatible with the solvent. A method in which polyvinyl chloride waste is recycled without mixing by mixing. Preferably, tetrahydrafuran is used as the solvent, and methanol, ethanol, or n-hexane is used as the precipitation medium. |
