Embodiment 1A

[0750] "Example 1A"

[0751] Mix 28 parts of graft copolymer (D-1A), 72 parts of styrene-based copolymer (H-1A), and 0.5 parts of carbon black (manufactured by Mitsubishi Chemical Corporation, "#966"), and use A twin-screw extruder with a vacuum valve (manufactured by Ikegai Co., Ltd., "PCM30") was melt-kneaded at a cylinder temperature of 220° C. and a vacuum of 93.325 kPa to prepare a thermoplastic resin composition (1A). The results of measuring the MVR of the obtained thermoplastic resin composition (1A) are shown in Table 15A.

[0752] Separately, 28 parts of graft copolymer (D-1A), 72 parts of styrene-based copolymer (H-1A), and 0.8 parts of carbon black (manufactured by Mitsubishi Chemical Corporation, "#966") were mixed and used A twin-screw extruder with a vacuum valve (manufactured by Ikegai Co., Ltd., "PCM30") was melt-kneaded at a cylinder temperature of 220° C. and a vacuum of 93.325 kPa to prepare a thermoplastic resin composition (2A).

[0753] The obtained ...

Embodiment 1B

[0915] Mix 24 parts of graft copolymer (D-1B) and 76 parts of methacrylate resin (G-1B), use A twin-screw extruder with a vacuum valve (manufactured by Ikegai Co., Ltd., "PCM30") was melt-kneaded at 240° C. and 93.325 kPa in vacuum to prepare a thermoplastic resin composition. The MVR of the thermoplastic resin composition is shown in Table 22B.

[0916] The thermoplastic resin composition is granulated, various molded products are molded, the flexural modulus is measured, and the impact resistance, heat resistance, gloss, color development, scratch resistance, and scratch resistance are evaluated. The results are shown in Table 22B.

Embodiment 2B～33B

[0918] Except having changed the kind of graft copolymer (D) as shown in Table 22B - Table 27B, it carried out similarly to Example 1B, prepared the thermoplastic resin composition, and measured MVR.

[0919] The thermoplastic resin composition is granulated, various molded products are molded, the flexural modulus is measured, and the impact resistance, heat resistance, gloss, color development, scratch resistance, and scratch resistance are evaluated. The results are shown in Table 22B to Table 27B.
