THERMOPLASTIC RESIN COMPOSITION AND MOLDED ARTICLE MANUFACTURED THEREFROM
Document Type and Number:
WIPO Patent Application WO/2023/054894
Kind Code:
A1
Abstract:
A thermoplastic resin composition according to the present invention comprises: approximately 100 parts by weight of a rubber-modified aromatic vinyl-based copolymer resin; approximately 5 to approximately 50 parts by weight of a polyester resin; approximately 20 to approximately 50 parts by weight of a polyetheresteramide block copolymer; approximately 0.05 to approximately 2.5 parts by weight of a silver (Ag)-based compound; and approximately 1 to approximately 20 parts by weight of zinc oxide, wherein the weight ratio of the polyetheresteramide block copolymer to the sum of the silver-based compound and the zinc oxide (polyetheresteramide block copolymer: silver-based compound + zinc oxide) is from approximately 1:0.1 to approximately 1:1. The thermoplastic resin composition has excellent antiviral properties, rigidity, heat resistance, impact resistance, thermal stability, antibacterial properties, and antifungal properties, etc.
