Beschreibung
Zusammenfassung:	A styrenic triblock copolymer composition with a combination of excellent tensile strength and high melt index, excellent for manufacturing, finishing and handling, forming stable pellets, for use in applications including but not limited to adhesive, coating, and flexographic printing. The composition comprises a first block which is a polymer of a monoalkenyl arene; a second block which is polymer of a conjugated diene and a third block which is a polymer of a monoalkenyl arene wherein a peak molecular weight of the third block is from about 0.06 to about 0.4 times that of the first block.
