  • Thermoplastic resin composition having good scratch resistance and molded article made therefrom
    Patent number: 8344043
    Abstract: The present invention provides a thermoplastic resin composition that can have improved scratch resistance comprising: (A) about 10 to about 20% by weight of a rubber modified aromatic vinyl graft copolymer resin; (B) about 30 to about 50% by weight of polymethylmethacrylate (PMMA) resin; and (C) about 40 to about 60% by weight of an aromatic vinyl copolymer resin including about 5 to about 50% by weight of a (meth)acrylate alkyl ester. The thermoplastic resin composition of the present invention can have a good balance of various properties such as scratch resistance, impact strength, colorability, gloss, and injection molding properties.
