ABSTRACT:
A method of recovering a vinyl chloride resin, which comprises mixing an aqueous dispersion of a vinyl chloride resin with an organic liquid which is difficultly soluble in water and does not dissolve nor swell the vinyl chloride resin to form a granular aggregate of the vinyl chloride resin, dehydrating the aggregate and drying it, wherein the granular aggregate before dehydration is adjusted to such a particle size that it contains not more than 20% by weight of particles having a particle diameter of not more than 100 microns.
