A polyolefin-polystyrene multi-block copolymer and a method of producing the same is disclosed herein. In some embodiments, the polyolefin-polystyrene multi-block copolymer has a first complex viscosity of 40,000 Pa·s to 350,000 Pa·s at a temperature of 160° C. and a first frequency of 0.5 rad/s, and has a second complex viscosity of 900 Pa·s to 3,500 Pa·s at a temperature of 160° C. and a second frequency of 125 rad/s. The polyolefin-polystyrene multi-block copolymer has a structure in which polystyrene chains are attached to both ends of a polyolefin chain.
A polyolefin-polystyrene multi-block copolymer satisfying conditions (a) and (b) below:
