しく低下させる原因となっていた。Obtaining a modified resin composition has been widely practiced. Among inorganic fillers, talc is particularly useful because it improves the hardness and strength of the product and also increases the heat distortion temperature of the product. However, when talc is used as a filler, the resulting product changes color to yellow or gray, and the whiteness is generally 0 (less than 0). In the case of polypropylene polymerized by the phase method, the color sometimes changes from dark green to green, causing a significant decrease in product value.

となり、本発明を完成するに至った。(Means for Solving the Problems) In view of the above-mentioned current situation, the present inventors have made extensive studies and found that by adding an inorganic substance with high whiteness as in the conventional method, the whiteness of the entire composition can be improved. Unlike methods that improve the color of polypropylene, it is now possible to add higher fatty acid bisamide, which is an organic substance, and utilize its chemical properties to suppress discoloration of the composition and obtain a polypropylene resin composition with high whiteness. The invention was completed.
