US 12,344,744 B2 · Polyarylene sulfide resin composition, molded article obtained by molding same, laminate, and production method thereof

Abstract

The present invention is a molded article containing a polyarylene sulfide resin, a thermoplastic resin other than the polyarylene sulfide resin, and a metal oxide containing at least one of copper or chromium. The polyarylene sulfide resin forms a continuous phase, and a dispersed phase containing the thermoplastic resin and the metal oxide is present in the continuous phase. The present invention is also a polyarylene sulfide resin composition for providing it, a molded article having a roughened surface, a laminate of the molded article and metal, and methods for producing them. According to the present invention, there is provided a molded article that has superior heat resistance of a polyarylene sulfide resin, on which the speed of plating deposition is practical, and with which a laminate with potentially maintained adhesiveness of plating can be obtained and a method for producing it, as well as a polyarylene sulfide resin composition.

Dependent claims

A molded article comprising a polyarylene sulfide resin, a thermoplastic resin, which is an aromatic polyamide resin, a metal oxide containing at least one of copper or chromium, and a layered and cleavable clay mineral,

wherein the polyarylene sulfide resin forms a continuous phase, and a dispersed phase containing the thermoplastic resin and the metal oxide is formed in the continuous phase, and
wherein more than 0% and 30% or less of the metal oxide in the molded article is present in the continuous phase,
and wherein the layered and cleavable clay mineral is more abundant in the dispersed phase like the metal oxide.

Dependencies are inferred from the claim text.
