Abstract
The present invention provides a block copolymer composition and method of making the same having the structures (A2-B)n—X-(A1) or (A2-B2)n—X—(B1A1), where A1 and A2 are each a polymer block of a monoalkenyl arene and B, B1, and B2 are each a polymer block of one or more conjugated dienes or a hydrogenated diene polymer, n is an integer from 2 to 30 and X is the residue of a coupling agent.
