Abstract
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 μm or more and 500 μm or less and an average degree of polymerization of 1,350 or more. The acrylic polymer has an average particle diameter of 0.01 μm or more and 10 μm or less and contains a constitutional unit derived from a (meth) acrylic ester in an amount of 50 mass % or more.
Claims12
A polyvinyl chloride composition for powder molding comprising:
- a polyvinyl chloride (A) in an amount of 100 parts by mass;
- a plasticizer in an amount of 110 to 150 parts by mass;
- and
- an acrylic polymer in an amount of 4 to 23 parts by mass,
- wherein the polyvinyl chloride (A) has an average particle diameter of 50 μm to 500 μm and an average degree of polymerization of 1,350 or more,
- wherein the acrylic polymer has an average particle diameter of 0.01 μm to 10 μm and contains a constitutional unit derived from a (meth)acrylic ester in an amount of 50 mass % or more,
- wherein the (meth)acrylic ester includes at least one selected from the group consisting of a (meth)acrylic ester of an aliphatic alcohol having two or more carbon atoms and a (meth)acrylic ester of an aromatic alcohol, and
- wherein the acrylic polymer contains a constitutional unit derived from methyl (meth)acrylate in an amount of 40 to 60 mass %, and a constitutional unit derived from at least one (meth)acrylic ester selected from the group consisting of n-butyl (meth)acrylate, isobutyl (meth)acrylate, and tert-butyl (meth)acrylate in an amount of 40 to 60 mass %.
