A polyvinyl chloride composition for powder molding includes a polyvinyl chloride (A) an amount of 100 parts by mass, a plasticizer in an amount of 110 parts by mass or more and 150 parts by mass or less, and an acrylic polymer in an amount of 4 parts by mass or more and 23 parts by mass or less. The polyvinyl chloride (A) has an average particle diameter of 50 &#x3bc;m or more and 500 &#x3bc;m or less and an average degree of polymerization of 1,350 or more. The acrylic polymer has an average particle diameter of 0.01 &#x3bc;m or more and 10 &#x3bc;m or less and contains a constitutional unit derived from a (meth) acrylic ester in an amount of 50 mass % or more.

Vinyl chloride resin composition for powder molding, vinyl chloride resin molded body and laminate

The present invention relates to a powder slush molded body of a polyvinyl chloride composition, the polyvinyl chloride composition containing a polyvinyl chloride, a plasticizer, and an acrylic polymer. The polyvinyl chloride composition contains the plasticizer in an amount of 110 parts by mass or more and 150 parts by mass or less with respect to 100 parts by mass of the polyvinyl chloride. When a cross section of the powder slush molded body extending in parallel with a thickness direction is observed under an optical microscope using reflected light, irregular scale-like polyvinyl chloride particles having a long diameter of 30 &#x3bc;m or more and 500 &#x3bc;m or less are continuous with one another via interfacial portions, and the number of aggregated particles of the acrylic polymer having a long diameter of 30 &#x3bc;m or more and 100 &#x3bc;m or less is 10 particles/mmor less. Thus, provided are a powder slush molded body of a polyvinyl chloride composition having high flexibility after heat aging as well as favorable surface characteristics, and a laminate.
