- There are problems such as inevitable deterioration in quality other than impact resistance due to the limited particle size.
- increasing the particle size of the graft polymer is known to cause a decrease in physical properties represented by the surface gloss of the molded product.
- the particle size of the impact resistance improver in the thermoplastic resin is large, the effect of increasing the stress concentration is obtained, but at the same time, the stress concentration decreases due to an increase in the interparticle distance.

- the range specified in the present invention it is possible to obtain a thermoplastic resin composition having a remarkably high impact resistance improving effect without lowering physical properties such as weather resistance and surface gloss of the molded product, that is, Even if the amount of the impact modifier is small, it is possible to obtain a thermoplastic resin composition having high impact resistance.
