Abstract:
1. A resin composition for pressure-foam molding, which comprises an ethylene-based copolymer and a foaming agent, wherein the ethylene-based copolymer has monomer units derived from ethylene and monomer units derived from an α-olefin having 3 to 20 carbon atoms, has a melt flow rate of 0.01 to 0.7 g/10 minutes, a molecular weight distribution of 5 or more determined by a gel permeation chromatography, an activation energy of flow of 40 kJ/mol or more, and inflection points of 3 or less on a melting curve within temperature range from 25° C. to the end point of melting obtained by a differential scanning calorimetry.
