Abstract: Foamable compositions and soft foams comprise at least an ethylene/?-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/?-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.

Abstract: Chaotic advection causes the formation of various encapsulates in binary phase composites. Such composites are successfully formed with thermoplastics that are present in desired amounts by weight or volume. With a batch type chaotic mixer, the process starts with selecting suitable polymers, mechanically mixing the raw material, heating the mixture, instilling chaotic advection by agitation for a period of time and cooling and recovering the composite. With continuous flow types of chaotic mixers, the process starts with melting the component polymers in separate extruders capable of component melt flows in predetermined proportions.
