<p>A novel block copolymer composition including a hydrogenated block copolymer that has at least one block A and at least one block B, and wherein ppor to hydrogenation each A block is a mono alkenyl arene homopolymer block and each B block is a controlled distribution copolymer block of at least one conjugated diene and at least one mono alkenyl arene. Total amount of mono alkenyl arene in the hydrogenated block copolymer is about 5 percent weight to about 50 percent weight, and the weight percent of mono alkenyl arene in each B block is between about 10 percent and about 75 percent. The thermoplastic polyurethane elastomer is present in the block copolymer in an amount from about 50 to about 95 percent by weight of a thermoplastic polyurethane elastomer.</p> |
