    摘要： Foamable compositions and foams comprise at least an ethylene/α-olefin interpolymer. The foam has a density from greater than 150 to about 500 kg/m3. The foamable compositions further comprise a blowing agent and a crosslinking 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 foams; and foamed articles made from the foams are also described.

    摘要： The present invention relates to compositions comprising blends of alkenyl aromatic polymers such as styrenic polymers (i.e. PS and HIPS) and bio-based or biodegradable polymers (i.e. PLA, PGA, PHA, PBS, PCL) compatibilized with styrene-based copolymers (i.e. styrene-ethylene-butylene-styrene (SEBS) block copolymers, maleated SEBS, styrene-maleic anhydride (SMA) copolymer, styrene-methyl methacrylate (SMMA) copolymer) or a mixture of two or more styrene-based copolymers such as SEBS and SMA. These novel compositions can be extruded and thermoformed to produce very low density food service and consumer foam articles such as plates, hinged lid containers, trays, bowls, and egg cartons with good mechanical properties.
