摘要： The present invention relates to a multi-block copolymer, a method for preparing same, and a thermoplastic resin composition comprising polypropylene and the multi-block copolymer. The block copolymer has excellent processability and excellent compatibility with polypropylene. Accordingly, a thermoplastic resin composition of the present invention, to which same is applied, exhibits excellent low-temperature impact strength, and thus, can be usefully used as a thermoplastic resin composition in the manufacture of products requiring high impact resistance, such as automobile parts.
