Key statement: The present invention provides a polymeric composition that includes a coupled block copolymer having a plurality of arms comprising at least two blocks of a monovinylaromatic hydrocarbon that are located on at least two of the plurality of arms, and at least one block of a conjugated diene located on at least one of the plurality of arms, and optionally one or more block copolymers comprising at least one block of monovinylaromatic hydrocarbon and at least one block of a conjugated diene, the block copolymer may be selected from linear copolymers, linear triblock copolymers, multiarm coupled block copolymers, and mixtures thereof.
The composition of the block copolymer was varied with regard to the number of HS, the concentration of HS, the position of the HS, and the molecular weight of the copolymers.
