摘要: Foamable compositions and soft foams comprise at least an ethylene/α-olefin interpolymer. The soft foam has a density from about 10 to 150 kg/m3. The foamable compositions further comprise a blowing agent. The ethylene/α-olefin interpolymers are a multi-block copolymer comprising at least one soft block and at least one hard block. Methods of making the foamable compositions and soft foams; and foam articles made from the soft foams are also described.
