Beschreibung
Zusammenfassung:	A block copolymer composition containing at least two alkenyl or alkenylidene aromatic terminal blocks, and at least one intermediate block based on a conjugated diene. A composition containing in parts by weight, 100 parts of a block copolymer comprising at least one conjugated diene block and at least two terminal monoalkenyl or monoalkylidene aromatic hydro carbon blocks; 5 to 125 parts of an impact polystyrene containing from 1 to 35% of an elastomeric component; 5 to 175 parts of a rubber extending hydrocarbon oil, and 0 to 250 parts of a finely divided filler. These compositions when used in footwear components, do not exhibit the phenomenon known as "elephant hide" found in known similar compositions.
