摘要：
An expandable poly(vinyl chloride) resin composition for use in powder molding process containing a granular poly(vinyl chloride) resin, a fine-granular poly(vinyl chloride) resin, a plasticizer, a stabilizer, a foaming agent and an alkyl phosphate gives by a powder molding process an expansion-molded article having remarkably strengthened foamed cells and free from the occurrence of surface unevenness caused by polyurethane backing.
