摘要： The present disclosure relates to a thermoplastic transparent resin composition for a wheel rust cover. The thermoplastic transparent resin composition is excellent in transparency and impact strength and suitable for a vacuum compression thermal molding process. A thermoplastic transparent resin composition for a wheel rust cover includes 20 wt % to 60 wt % of a graft copolymer, 40 wt % to 70 wt % of a non-graft copolymer, and 3 wt % to 10 wt % of a processing aid, in which a total rubber content is 10 wt % to 25 wt %, a total methacrylic acid alkyl ester compound content is 34 wt % to 67 wt %, a total aromatic vinyl compound content is 16 wt % to 40 wt %, and a total vinyl cyan compound content is 0 wt % to 10 wt %.

摘要： The present invention relates to a graft copolymer having excellent thermal stability, a method of preparing the graft copolymer, a thermoplastic resin composition including the graft copolymer, and a molded part including the thermoplastic resin composition. According to the present invention, since the thermoplastic resin composition of the present invention includes the graft copolymer having excellent thermal stability, the thermoplastic resin composition and the molded part manufactured using the thermoplastic resin composition have excellent physical properties, such as impact strength, fluidity, and transparency. Furthermore, the degree of discoloration that may occur when the resin composition or the molded part is allowed to stay in an injection molding machine or stay at a high temperature for a long period of time may be reduced.

摘要： Disclosed are a thermoplastic resin composition and a method of preparing the same. More particularly, the present invention relates to a thermoplastic resin composition including 10 to 90% by weight of a graft copolymer resin coagulated by an organic acid or an organic acid salt; and 90 to 10% by weight of a non-graft copolymer resin and having a moist-heat characteristic of 20 or less, wherein a refractive index difference between the graft copolymer resin and the non-graft copolymer resin is less than 0.01, a method of preparing the same, and a molded product comprising the same. According to the present disclosure, provided are a thermoplastic resin composition having superior overall property balance, color, and transparency, and being applicable to products that are exposed to high-temperature water or should be sterilized, due to excellent moist-heat resistance thereof, a method of preparing the same, and a molded product comprising the same.
