PROBLEM TO BE SOLVED: To provide a vinyl chloride hollow particle which can achieve weight reduction of vinyl chloride molded product while keeping excellent characteristics of vinyl chloride itself, and also secondary processability, and to provide its manufacturing method, a vinyl chloride resin composition containing the hollow particle, and a vinyl chloride plate obtained by using the vinyl chloride resin composition.;SOLUTION: The manufacturing method of vinyl chloride hollow particle includes (1) mixing a monomer component containing vinyl chloride and a polyfunctional monomer as a principal component, a polymerization initiator, and a dispersant into a polar solvent to prepare a suspension, (2) heating the suspension and polymerizing the monomer component to remove unreacted vinyl chloride when the polymerization of the monomer component is 75% or less, thereby forming a resin particle, and (3) dehydrating and drying the resin particle.;COPYRIGHT: (C)2011,JPO&INPIT
