Document Type and Number:

WIPO Patent Application WO/2018/124517

Kind Code:

A1

Abstract:

The present invention relates to a thermoplastic resin composition, a preparation method therefor and a manufactured molded article containing same, and more specifically, the present invention provides a thermoplastic resin composition, a preparation method therefor and a manufactured molded article containing same, the thermoplastic resin composition containing a specific amount of: an ASA-based graft copolymer having a core-shell structure and an average particle diameter of 0.05 to 1 µm; an aromatic vinyl compound-vinyl cyanide compound copolymer; and an epoxy group-containing copolymer having a weight average molecular weight of 2,000 to 8,000 g/mol, and thus the thermoplastic resin composition has low-gloss properties while also exhibiting excellent weather resistance and mechanical properties such as tensile strength and impact strength.
