| titleOfInvention | Polypropylene resin molded article excellent in transparency and rigidity and method for producing the same |
| abstract | PROBLEM TO BE SOLVED: To provide a polypropylene resin molded article excellent in transparency and rigidity and a method for producing the same. SOLUTION: The molten resin is heated to 50 ° C. using a mold having a center line average roughness Ra (mold) of 0.1 μm or less and a thermal conductivity of 100 W / m · K or more on a surface in contact with the molten resin. After cooling and solidifying to a molded body to the following, the molded body is heated to 60 ° C. or more and 150 ° C. A method for producing a polypropylene resin molded article, wherein a heat quantity of 20 J / g or more is given at a temperature in the following range. And a diffraction pattern obtained by wide-angle X-ray diffraction obtained by the production method exhibits a monoclinic (α-crystal) structure, and a tissue structure of 5 μm or more is not observed by a light scattering method. Is 60% by weight or more, and the crystal thickness Lc represented by the product (χ · L / 100) of the crystallinity χ and the long period L obtained by small-angle X-ray scattering is 9%. A polypropylene resin molded article excellent in transparency and rigidity that satisfies that the tensile modulus E is 1400 MPa or more, which is not less than 1 nm. |
