ETHYLENE/ALPHA-OLEFIN COPOLYMER FOR FOAM PRODUCTION, RESIN COMPOSITION FOR FOAM PRODUCTION, AND METHOD FOR PRODUCING FOAM

摘要

The ethylene-α-olefin copolymer contains monomer units derived from ethylene and monomer units derived from anα-olefin having 3 to 20 carbon atoms for producing a foam. The ethylene-α-olefin copolymer has a melt flow rate of 0.1 to 100 g/10 minutes, a density of 850 to 940 kg/m3, a molecular weight distribution of 2 to 12, a swell ratio of 1.61 or more, and a value of g* as defined by a formula (I) of 0.50 to 0.78.
