The present invention relates to a method for producing a thermoplastic resin composition having excellent natural color. More specifically, polybutadiene rubber latex is graft copolymerized with methacrylic acid alkyl ester compound, aromatic vinyl compound, vinyl cyanide compound and the like, and the refractive index is optimized by controlling the mixing ratio of monomers, so that the impact resistance, chemical resistance, processability, etc. are excellent, and transparency is excellent. A method for producing this extremely excellent thermoplastic resin composition.n n n The composition of the present invention is a polybutadiene rubber latex compound having a particle diameter of 2500 kPa to 5000 kPa, a gel content of 60% to 95%, and a swelling index of 12 to 40, and a monomer to be grafted thereto. It consists of an aromatic vinyl compound and a vinyl cyanide compound, and is manufactured by the emulsion polymerization method. |
