Abstract
A styrene-isoprene/butadiene diblock copolymer contains a polystyrene block and a polyisoprene/butadiene block. Based on 100 wt % of the styrene-isoprene/butadiene diblock copolymer, the polystyrene block is 20-45 wt %, and the polyisoprene/butadiene block is 55-80 wt %. The polyisoprene/butadiene block has a polyisoprene unit and a polybutadiene unit. The weight ratio of the polyisoprene unit to the polybutadiene unit is 8:2 to 2:8.
