Abstract
The present disclosure relates to a thermoplastic resin composition, a method of preparing the same, and a molded article including the same. For example, the present disclosure relates to a thermoplastic resin composition including 35 to 85% by weight of an alkyl acrylate-aromatic vinyl compound-vinyl cyanide compound graft copolymer (A) containing alkyl acrylate rubber having an average particle diameter of 50 to 120 nm and 15 to 65% by weight of a polymethacrylate resin (B). The thermoplastic resin composition has an alkyl acrylate coverage value (X) of 70% or more as calculated by Equation 1. The thermoplastic resin composition may have beneficial mechanical properties, such as impact strength, tensile strength, and flexural strength, surface hardness, transparency, and colorability and may be capable of preventing occurrence of whitening during bending due to beneficial non-whitening properties.
