    摘要: The crosslinked material of the present invention is obtainable by crosslinking a propylene resin composition through irradiation with an ionizing radiation wherein the propylene resin composition comprises 100 parts by mass of a propylene resin comprising 15 to 99% by mass of a propylene polymer (A) having a melting point, as measured by a differential scanning calorimeter (DSC), of 120 to 170° C., and 1 to 85% by mass of propylene polymer (B) having a melting point, as measured by a differential scanning calorimeter (DSC), of below 120° C. or not observed (provided that the total of the components (A) and (B) is 100% by mass), and 0.1 to 5 parts by mass of a crosslinking assistant (C). The production process of the crosslinked material of the present invention comprises a step of molding the propylene resin composition into a molded form, and a step of crosslinking the molded form through irradiation with an ionizing radiation. The crosslinked molded article of the present invention is formed from the crosslinked material.
