VINYL CHLORIDE-BASED HOLLOW PARTICLE, METHOD FOR MANUFACTURING THE SAME, VINYL CHLORIDE-BASED RESIN COMPOSITION, AND VINYL CHLORIDE-BASED MOLDING

摘要

PROBLEM TO BE SOLVED: To provide a vinyl chloride-based hollow particle reducing the weight as a vinyl chloride-based molded material while securing superior characteristics of vinyl chloride itself and securing secondary workability, too, to provide a method for manufacturing the vinyl chloride-based hollow particle, to provide a vinyl chloride-based resin composition containing the hollow particle, and to provide a vinyl chloride plate obtained by using the vinyl chloride-based resin composition.;SOLUTION: The vinyl chloride-based hollow particle is obtained by performing suspension polymerization in a system including a monomer component containing the vinyl chloride as principal component and a polyfunctional monomer, a polymerization initiator and a dispersant, and has porosity of 40% or more. There is also provided the molding formed of the vinyl chloride-based resin composition containing the vinyl chloride-based hollow particle.;COPYRIGHT: (C)2011,JPO&INPIT
