Abstract
A thermoplastic resin composition includes a polyester resin (A); a vinyl cyanide compound-conjugated diene compound-aromatic vinyl compound graft copolymer (B); an alpha-methylstyrene-vinyl cyanide compound copolymer (C); a maleimide-based polymer (D); and an amide-based lubricant (E), A method of preparing the thermoplastic resin composition, and a molded article including the thermoplastic resin composition are also described.
Claims19
A thermoplastic resin composition, comprising:
- a polyester resin (A),
- a vinyl cyanide compound-conjugated diene compound-aromatic vinyl compound graft copolymer (B),
- an alpha-methylstyrene-vinyl cyanide compound copolymer (C),
- a maleimide-based polymer (D), and
- an amide-based lubricant (E).
A thermoplastic resin composition, comprising, based on a total weight of the thermoplastic resin composition:
- 20 to 40% by weight of a polyester resin (A) having an intrinsic viscosity of 1.1 dl/g or more;
- 15 to 30% by weight of a vinyl cyanide compound-conjugated diene compound-aromatic vinyl compound graft copolymer (B);
- 20 to 35% by weight of an alpha-methylstyrene-vinyl cyanide compound copolymer (C);
- 10 to 20% by weight of a maleimide-based polymer (D);
- and
- 0.1 to 5% by weight of a lubricant (E),
- wherein the weight of the polyester resin (A) is not less than the weight of the vinyl cyanide compound-conjugated diene compound-aromatic vinyl compound graft copolymer (B).
A method of preparing a thermoplastic resin composition, comprising:
- melt-kneading, and extruding a polyester resin (A), a vinyl cyanide compound-conjugated diene compound-aromatic vinyl compound graft copolymer (B), an alpha-methylstyrene-vinyl cyanide compound copolymer (C), a maleimide-based polymer (D), and an amide-based lubricant (E), at 200 to 300° C.
The method according to claim 116, wherein the thermoplastic resin composition comprises, based on a total weight of the thermoplastic resin composition:
- 20 to 40% by weight of the polyester resin (A);
- 15 to 30% by weight of the vinyl cyanide compound-conjugated diene compound-aromatic vinyl compound graft copolymer (B);
- 20 to 35% by weight of the alpha-methylstyrene-vinyl cyanide compound copolymer (C);
- 10 to 20% by weight of the maleimide-based polymer (D);
- and/or
- 0.1 to 5% by weight of the amide-based lubricant (E).
