VINYL CHLORIDE RESIN AGGREGATE PARTICLES, PROCESS FOR PRODUCING SAME, AND GLOVE OBTAINED USING SAME

摘要

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 aggregate particles of the present invention are characterized in that the aggregate particles have a mean volume particle diameter of 10 to 60 mum, the percentage of particles having a particle diameter of 10 to 60 mum is at least 50 vol. %, and a plastisol containing 100 weight parts of the aggregate particles and 160 weight parts of di-2-ethylhexyl phthalate satisfies the relationship 3@eta70/eta40@1000 where eta40 is the viscosity at a shear rate of 1 s-1 of the plastisol that has been retained at 40° C. for 10 minutes and eta70 is the viscosity at a shear rate of 1 s-1 of the plastisol that has been warmed from 40° C. at 10° C./min. and retained at 70° C. for 3 minutes. 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.
