Abstract:
1. An adhesive composition comprising: a block copolymer consisting of a triblock (A-B-A′) and a diblock (B′-A′) represented by the following Formula I, a hydrocarbon adhesive resin, and a plasticizer wherein A and A′ are vinyl aromatic monomer polymers, B and B′ are conjugated diene polymers, n and m are independently a weight average mixed ratio of a triblock [A-B-A′] and a diblock [B′-A′] (here, n+m=100 weight %, and n≧m, m≧1), wherein the weight average molecular weight of the diblock is smaller than that of the triblock and is larger than that of A constituting the triblock, wherein the molecular weight distribution (MWD) of the diblock is larger than 1.1 and smaller than 2.0, wherein the diblock has two or more peak molecular weights (Mp).
