Title:
RECYCLED STYRENE-BASED RESIN COMPOSITION, MOLDED ARTICLE THEREOF, AND CARTRIDGE
Document Type and Number:
WIPO Patent Application WO/2024/080342
Kind Code:
A1
Abstract:
The problem to be solved by the present disclosure is to provide a recycled styrene-based resin composition that reduces environmental load, suppresses a decrease in mechanical strength and chemical resistance, and exhibits excellent appearance and thermal creep resistance properties, and to provide a molded article obtained using the same. The present disclosure is a recycled styrene-based resin composition comprising: a recycled polystyrene-based resin (A) containing a toluene-insoluble portion (1) after an osmium tetroxide treatment; and a rubber modified polystyrene-based resin (B) containing rubber-like polymer particles (b2) constituting a domain phase and a polystyrene-based resin (b1) constituting a polymer matrix phase. The content of the toluene-insoluble portion (1) after the osmium tetroxide treatment is from greater than 0 to 10 mass% with respect to the entire recycled styrene-based resin composition.
