Abstract
The present invention provides: vinyl chloride-based resin aggregate particles that can be produced through a heat treatment while inhibiting scale formation within a vessel for the heat treatment and that provide a plastisol with non-infiltrating property and a satisfactory sagging property; a process for producing the particles; and a glove obtained using the particles. The vinyl chloride-based resin aggregated particles are obtained by flocculating a vinyl chloride-based resin through a two-stage heat treatment consisting of a primary heat treatment and a secondary heat treatment.
