POLYARYLENE SULFIDE RESIN COMPOSITION, MOLDED ARTICLE, AND METHODS FOR PRODUCING THESE

WIPO Patent Application WO/2023/074035

A1

Provided are: a polyarylene sulfide (PAS) molded article having especially exceptional toughness, the PAS molded article including a PAS resin as well as a thermoplastic elastomer and/or a silane coupling agent; a PAS resin composition that makes it possible to provide the molded article and has exceptional workability such that thickening and generated gas caused by residence are suppressed; and methods for producing the PAS molded article and the PAS resin composition. More specifically: a PAS resin composition obtained by blending a PAS resin with a thermoplastic elastomer and/or a silane coupling agent, the PAS resin composition being characterized in that the PAS resin is a crosslinked PAS resin and has a region in which tanδ is less than 1 at 280-330°C at an angular frequency of 1/s in dynamic viscoelasticity measurement, the amount of thermoplastic elastomer blended is within the range of 12 parts by mass or less per 100 parts by mass of PAS resin and/or the amount of silane coupling agent blended is within the range of 1.0 part by mass or less per 100 parts by mass of PAS resin, and the viscosity change rate is 150% or less; a molded article; and methods for producing the PAS resin composition and the molded article.
