Abstract
The present method for producing a crosslinked product include the steps of: melt molding an ethylene copolymer (A) or a resin composition containing the ethylene copolymer (A); and carrying out crosslinking; wherein the ethylene copolymer (A) contains a constitutional unit derived from ethylene and a constitutional unit derived from an α-olefin having 3 to 20 carbon atoms, and satisfies the following requirements (1), (2) and (3): (1) a vinyl group content per 1,000 carbon atoms as measured by 1H-NMR is from 0.06 to 1; (2) a ratio MFR10/MFR2.16 is from 8.5 to 50; and (3) a density d is from 850 kg/m3 to 920 kg/m3. The present method for producing a crosslinked product is capable of providing a crosslinked product having a good moldability and an excellent mechanical strength. Further, the present method is capable of providing a foamed product which is light weight and excellent in mechanical strength, with an excellent productivity; as well as providing crosslinked molded articles whose dimensional variations between individual products are small.
