    摘要： The present invention relates to a thermoplastic resin composition, a method of preparing the same, and a molded article including the same. More specifically, the thermoplastic resin composition of the present invention includes 65 to 85 % by weight of a heat-resistant copolymer (A) containing 76 to 92 % by weight of a (meth)acrylic acid alkyl ester compound, 1 to 8 % by weight of an N-substituted maleimide compound, and 5 to 16 % by weight of an aromatic vinyl compound; 10 to 30 % by weight of an acrylate-based rubber-aromatic vinyl compound-vinyl cyanide compound graft copolymer (B) containing acrylate-based rubber having an average particle diameter of 50 to 200 nm; and 1 to 15 % by weight of an acrylate-based rubber-aromatic vinyl compound-vinyl cyanide compound graft copolymer (C) containing acrylate-based rubber having an average particle diameter of 300 to 600 nm. In this case, in the heat-resistant copolymer (A), the weight ratio of the aromatic vinyl compound to the N-substituted maleimide compound is 1.5 to 8. Within this range, a thermoplastic resin composition having excellent weather resistance, heat resistance, colorability, processability, and scratch resistance, a method of preparing the thermoplastic resin composition, and a molded article including the thermoplastic resin composition may be provided.

    摘要： The present invention provides a styrene-acrylonitrile (SAN) resin that exhibits significantly improved thermal resistance and, at the same time, can be produced at high productivity and is highly processable and highly moldable; and a method of producing the same by preparing and storing the solution containing a mixture of an N-substituted maleimide monomer and an unsaturated nitrile monomer at a particular temperature, introducing the solution and a styrene polymer into the polymerization reactor separately, and maintaining the first polymerization reactor and the second polymerization reactor at particular respective temperatures, thereby significantly reducing the amounts of oligomers contained in the SAN resin.

    摘要： The present invention relates to a method of preparing a styrene-based resin having a low oligomer content and a styrene-based resin prepared thereby. The preparation method according to the present invention may prepare a styrene-based resin having a reduced oligomer content by using a polymerization initiator having a 1 hour half-life temperature, which is 5°C to 25°C lower than a temperature during polymerization, and controlling devolatilization conditions.
