WIPO Patent Application WO/2022/158709
Kind Code:
A1
Abstract:
The present disclosure relates to a thermoplastic resin composition, a method of preparing same, and a molded article comprising same, and more specifically, to a thermoplastic resin composition, a method of preparing same, and a molded article comprising same, the thermoplastic resin composition comprising: (A) 25 to 75 wt% of an alkyl acrylate-aromatic vinyl compound-vinyl cyan compound graft copolymer, comprising an alkyl acrylate rubber having an average particle size of 50 to 120 nm; and (B) 25 to 75 wt% of a (meth)acrylic acid alkyl ester compound-aromatic vinyl compound-vinyl cyan compound-vinyl cyan compound non-graft copolymer, wherein an alkyl acrylate coverage value (X) calculated by equation 1 is 67% or more. According to the present invention, provided is a thermoplastic resin composition which has mechanical properties such as impact strength, tensile strength, and flexural strength, comparable or superior to a conventional ASA-based resin, and has excellent transparency, tinting properties, and whitening resistance resistant to whitening when bent, and thus has an excellent outer appearance. In addition, the present invention provides a method of preparing the thermoplastic resin composition, and a molded article comprising the thermoplastic resin composition.
