Beschreibung
Zusammenfassung:	A recovery method of vinyl chloride resin which comprises formulating an aggregate of vinyl chloride resin by adding to an aqueous dispersion of vinyl chloride resin an organic liquid which is difficultly soluble in water and does not dissolve or swell vinyl chloride resin and mixing the two; dehydrating the aggregate; and drying the same to recover granular vinyl chloride resin, the characteristic feature residing in that said aqueous dispersion is the one which has passed through the screen of 20 to 150-micron meshes.
