The method for producing a crosslinked body of the present invention comprises the steps of: forming a copolymer having a constituent unit derived from ethylene and a constituent unit derived from an α-olefin having 3 to 20 carbon atoms and satisfying the following (1), (2) And the step of melt-molding the ethylene-based copolymer (A) or the resin composition containing the ethylene-based copolymer (A), and the step of crosslinking the resin composition (A).n(1) The vinyl content per 1000 carbon atoms determined by 1H-NMR is 0.06 or more and one or less.n(2) MFR10/MFR2.16 is 8.5 or more and 50 or less.n(3) The density d is 850 kg/m3 or more and 920 kg/m3 or less.nAccording to the method for producing a crosslinked body of the present invention, a crosslinked body having good moldability and excellent mechanical strength can be obtained. Further, a foam having excellent lightness and excellent mechanical strength can be obtained by a method excellent in productivity, and a crosslinked molded article having a small size unevenness between individuals can be provided. |
