Abstract
PURPOSE:To obtain a PVC resin composition pellet which provides pre-expanded particles which can be used in highly productive in-mold expansion molding without using any processability improver etc., by mixing PVC with an inorganic substance, a solvent and a blowing agent. CONSTITUTION:The title pellet is prepared by adding an inorganic substance (e.g., talc or CaCO3), a solvent (e.g., cyclohexanone) and a blowing agent (e.g., dicyclodifluoromethane) to PVC (e.g., vinyl chloride homopolymer or copolymer of a vinyl chloride content >=50wt.%). This pellet contains a solvent compatible with PVC, whereby domain particles or microdomain articles in the PVC particles can be disintegrate to a size of a molecular and the porousness of the PVC particles can be eliminated to give thereto improved retentivity of a blowing gas and the permit the production of pre-expanded particles which can be used in highly productive in-mold expansion molding without using any processability modifier etc.
