Abstract

The present disclosure relates to a thermoplastic resin composition providing superior low-gloss characteristic, weather resistance, and mechanical properties and an extruded article manufactured from the same. More particularly, the present invention relates to a thermoplastic resin composition including 40 to 70% by weight of an aromatic vinyl compound-vinyl cyan compound copolymer as a matrix resin; 20 to 40% by weight of an acrylic graft copolymer (a) in which 46 to 95% by weight of an aromatic vinyl compound-vinyl cyan compound copolymer is grafted to 5 to 54% by weight of a (meth)acrylate-based rubbery polymer having an average particle diameter of 0.05 to 1 μm; 1 to 10% by weight of an acrylic graft copolymer (b) in which 5 to 45% by weight of an aromatic vinyl compound-vinyl cyan compound copolymer is grafted to 55 to 95 % by weight of a (meth)acrylate-based rubbery polymer having an average particle diameter of 0.05 to 1 μm; and 1 to 20% by weight of a large-diameter diene-based graft copolymer (c) in which 80 to 95% by weight of an aromatic vinyl compound-vinyl cyan compound copolymer is grafted to 5 to 20% by weight of a diene-based rubbery polymer having an average particle diameter of 1 to 20 μm, and thus, providing superior low-gloss characteristic, weather resistance, and mechanical properties, and an extruded article manufactured from the same.
