method of manufacturing polypropylene-based resin molded article including a method of controlling the crystallization of the amide compound, obtained by the production method polypropylene resin molded articles, and its secondary processing molded article

摘要

Promote the crystallization of needle-like crystals of amide compounds present in the polypropylene-based resin was and how huge the crystals (enlarged) inhibits when molding the polypropylene resin composition, a method of producing the polypropylene-based resin molded article including the methods, and polypropylene-based resin molding which is obtained by the production process It provides the body and its secondary processing molding. A method of manufacturing a polypropylene-based resin molded article comprising a step of molding the molten polypropylene resin composition, a crystal of a specific amide compound present in the polypropylene resin in a molten state, furthermore, the molten polypropylene resin in, with the amide compound, a manufacturing method of polypropylene resin moldings which is characterized by the coexistence of at least one fatty acid calcium salt selected from the saturated and the group consisting of fatty acid calcium salts of unsaturated carbon atoms 22-32 It is.
