PURPOSE:To obtain an extrusion-molded article, blow-molded article or rotation- molded article of a crosslinked polyphenylene sulfide resin having good moldability and giving a molded article having excellent appearance and toughness. CONSTITUTION:This molded article of a crosslinked polyphenylene sulfide resin is produced by the extrusion, blow or rotational molding of a polyphenylene sulfide resin having a melt-viscosity of 1,000-100,000 poise (at 315.6 deg.C under a shearing rate of 100sec<-1>) and produced by the heat-treatment of a polyphenylene sulfide resin free from thermal crosslinking and having a melt viscosity of >=150 poise (at 315.6 deg.C under a shearing rate of 100sec<-1>) in solid phase under a heat-treatment condition comprising the evacuation degree of 0.1-600 Torr and the heat-treatment temperature of >=150 deg.C and below the melting point. |
