Document Type and Number:
WIPO Patent Application WO/2021/215488
Kind Code:
A1
Abstract:
Provided are a molded article having excellent antiviral activity, a method for producing the molded article with good processability, and also a masterbatch and a resin composition which can be used for said molded article and manufacturing method, and methods for manufacturing the masterbatch and resin composition. More specifically, the invention relates to a method for manufacturing a resin composition, which comprises a step of melt-kneading a thermoplastic resin and a metal compound composite to manufacture a masterbatch, and a step of melt-kneading a thermoplastic resin into the obtained masterbatch, wherein the metal compound composite includes titanium oxide that includes crystalline rutile-type titanium oxide and has a specific surface area within the range of 3 m2/g or more, and a divalent copper compound, and also relates to a resin composition having a maximum particle size in the range of less than 45 µm, a molded article, and methods for producing the resin composition and the molded article.
