PROBLEM TO BE SOLVED: To provide a polypropylene resin composition for foam molding or a foamable polypropylene resin composition capable of obtaining a uniform and dense foam cell (cell) and a foam having a high expansion ratio. It is an object of the present invention to provide a product, a foam obtained using the composition, a method for producing the foam, and a foam molded product obtained by thermoforming the foam. SOLUTION: It is manufactured using a metallocene catalyst system, A resin composition comprising a propylene / α, ω-diene copolymer containing 0.00001% to 2% by weight of α, ω-diene and a foaming agent is produced, and the resin composition is heated and melted. The mixture is kneaded and foamed to form a foam, and the foam is molded to form a foam. |
