Abstract
A thermoplastic resin composition according to the present invention contains about 100 parts by weight of a polycarbonate resin, about 5 to about 50 parts by weight of a polyolefin resin, about 5 to about 50 parts by weight of a glass fiber, and about 1 to about 20 parts by weight of a modified olefin-based copolymer, wherein the modified olefin-based copolymer includes an epoxy-modified olefin-based copolymer and a maleic acid anhydride-modified olefin-based copolymer, and the weight ratio of the epoxy-modified olefin-based copolymer to the maleic acid anhydride-modified olefin-based copolymer is about 1:0.05 to about 1:15. The thermoplastic resin composition has excellent stiffness, impact resistance, and the like, and has a low specific gravity, dielectric constant, dielectric dissipation factor, and the like.
