    Abstract: The present disclosure relates to a thermoplastic resin composition and a molded article including the same. More particularly, the present disclosure relates to a thermoplastic resin composition including 100 parts by weight of a styrene-based resin and 1 to 10 parts by weight of a surface modifier and having a skewness (Rsk) of 0.65 to 1.35 and a molded article including the thermoplastic resin composition. In addition, the present disclosure provides a thermoplastic resin composition that is capable of imparting a rough feeling to the surface of a product and has excellent weather resistance while maintaining mechanical properties and processability equal or superior to those of conventional ASA resins; and a molded article including the thermoplastic resin composition. In particular, due to these properties of the thermoplastic resin composition, a product manufactured using the thermoplastic resin composition may have a luxurious appearance without an artificial plastic feel.

    Abstract: The present disclosure relates to a thermoplastic resin composition and an exterior material including the same. The thermoplastic resin composition includes 100 parts by weight of styrene-based resins; 0.5 to 5 parts by weight of a first polyamide resin having a melting temperature (Tm) of 230° C. or less; and 0.5 to 10 parts by weight of a second polyamide resin having a melting temperature (Tm) of 250° C. or more. Both the first and second polyamide resins have a relative viscosity of 2.5 or less. The present disclosure advantageously provides a low-gloss thermoplastic resin composition having excellent aesthetics, such as softness, luxuriousness, and naturalness, due to uniform and low gloss, and improvement in surface texture while having mechanical properties and processability equal or superior to those of conventional ASA resins; and an exterior material including the low-gloss thermoplastic resin composition.
