Abstract
Poly(phenylene sulfide) (PPS) resins are known to show excellent heat resistance, chemical resistance, flame retardance, and mechanical property, and therefore, have been applied to various molding compound such as electric parts for automobile. On the other hand, the poor bonding ability with various adhesives and adhesive property with other materials are disadvantages of PPS resins. In this paper, we studied in the improvement in adhesive property of PPS resins by the addition of special epoxy resins, which were obtained by the glycidyl etherification of secondary hydroxyl groups of bisphenol A-type epoxy resins. As a result, the obtained PPS resin composition was found to show excellent mechanical and adhesive properties.
