Abstract
The present invention aims at modifying a polyblend mainly comprising a polycarbdnate resin and a polystyrene resin into a thermoplastic resin composition having flowability and impact strength equivalent to those of a polyblend comprising a polycarbonate resin and an ABS resin, and at providing a harmless flame-retardant thermoplastic resin composition based-on the resulting modified composition. Specifically, the present invention relates to a thermoplastic resin comprising 100 parts by weight of a-resin mixture comprising 30 to 95% by weight of a polycarbonate resin (a), 5 to 70% by weight of a polystyrene resin (b), 0.5 to 20 parts by weight of a specific block copolymer (c) and, if necessary, 0.1 to 20 parts by weight of a polyalkylene terephthalate (d), and/or 0.1 to 20 parts by weight of a polyphenylene ether resin (e), and a flame-retardant thermoplastic resin composition prepared by blending the above composition with 1 to 40 parts by weight of an organophosphorus compound (f) and, if necessary, 0.05 to 5 parts by weight of a fluoroethylene polymer (g).
