た。(Conventional technology and its problems) Conventionally, due to its excellent properties, vinyl chloride polymers have been used in a wide range of applications by adding various compounding agents according to the properties required in the final product, molding and processing. There is. Among these compounding agents, finely powdered silica is used for the purpose of increasing the bulk specific gravity in the molding and processing step of the vinyl chloride resin compound, preventing the charging property, improving the powder fluidity, and improving the bite into the extrusion screw. So-called antiblocking agents such as talc, hydrotalcite, barium carbonate, barium hydroxide, calcium stearate, barium stearate and zinc stearate may be used. However, when it is attempted to produce a transparent molded article using these antiblocking agents, there is a drawback that the turbidity increases.
