It has been clarified that the toughness (elongation) after the history (80 ° C ⁇ 48 hours) results in a resin molded body maintained at a high level.
- the hydrogenated block copolymer used as an admixture between the polypropylene resin and the polyphenylene ether resin if the number average molecular weight of the polymer block A mainly composed of a vinyl aromatic compound is less than 15,500, The condition that the short axis diameter of the dispersed particles composed of the diene ether resin and the hydrogenated block copolymer is 2 ⁇ m or less, and the ratio of the long axis diameter Z to the short axis diameter is 1 to 10 cannot be satisfied.
- the resulting resin composition has low heat creep resistance, impact resistance, and heat resistance (DTUL), which is not preferable.
- the short axis diameter of the dispersed particles composed of the polyphenylene ether resin and the hydrogenated block copolymer is 2 m or less, and the long axis
- the resin composition of the present invention that satisfies the condition that the ratio of the minor axis diameter is 1 to 10 has a higher moisture permeability per 1 mm in thickness than the resin composition that does not satisfy such a condition. It has clearly been found to result in less resin moldings. Therefore, the resin composition of the present invention is maintained at a high level of a balance between physical properties such as heat resistance creep resistance, toughness (elongation) after heat history (80 ° C. ⁇ 48 hours), and water vapor permeability resistance. . Furthermore, when high-crystalline polypropylene and medium-crystalline polypropylene are used together as a polypropylene resin, a greater synergistic effect can be seen.
- FIG. 1 is a perspective view of a battery case (battery case) 2 of a secondary battery.
- a plurality of ribs 11, 12, and 13 were formed on the outer surface of the battery case 2.
- the separator 2 containing the electrolyte was stored in the battery case 2 (electrode group) 4, and the cathode lead 5 and the anode lead 6 were pulled out from each of these electrode groups (FIG. 2).
- the lid (battery case lid) was heat-sealed together with 1, and the inside of the battery case was closed tightly.
