- the resin compositions of Examples 1 to 5 prepared using the block copolymers prepared in Preparation Examples 1 to 4 of the present invention have a spherical shape of the domain region, and the size and Because the distance between the plurality of domain regions was met, it was confirmed that the low-temperature impact strength was excellent, and from this, it could be predicted that the room temperature impact strength was also excellent.
- Comparative Examples 1 and 2 were prepared using Kraton's G1645, a commercially available styrene-ethylene-butylene-styrene block copolymer (SEBS), instead of the block copolymers prepared in Preparation Examples 1 to 4 of the present invention. It was confirmed that the resin composition of the domain region had a cylindrical shape, the size of the domain region was small, and the distance between the plurality of domain regions was narrow. For this reason, the styrene-ethylene-butylene-styrene block copolymer in the resin composition has the same content as the block copolymer prepared in Preparation Examples 1 to 4, as in the resin composition prepared in Examples 1 and 3 to 5 of the present invention.
- SEBS commercially available styrene-ethylene-butylene-styrene block copolymer
- Comparative Example 1 including (SEBS), it was confirmed that the low-temperature impact strength was extremely poor.
- SEBS styrene-ethylene-butylene-styrene block copolymer
- the resin composition in which the dispersibility of the block copolymer was adjusted by adjusting the size of the domain region and the distance between the plurality of domain regions had excellent impact strength at room temperature and low temperature. Accordingly, the present invention It was confirmed that the resin composition had excellent impact resistance at both room and low temperatures.
