摘要
A styrene-isoprene-styrene triblock copolymer, a method for manufacturing the same, a composition, and an adhesive composition using the same are provided. The styrene-isoprene-styrene triblock copolymer includes a first polystyrene block, a polyisoprene block, and a second polystyrene block. Based on 100 wt % of the styrene-isoprene-styrene triblock copolymer, the content of the first polystyrene block and the second polystyrene block is 30-50 wt %, and the content of the polyisoprene block is 70-50 wt %. The weight average molecular weight (Mw) of the styrene-isoprene-styrene triblock copolymer is 40,000-75,000.
