PURPOSE:To improve the heat resistance of a molded product which is obtained from a resin composition of polyarylene sulfide resin (PAS resin) and thermoplastic polyester. CONSTITUTION:A molded product is obtained by thermally treating a molded product obtained by molding 60 pts.wt. of PAS resin, e.g. polyphenylene sulfide and thermoplastic polyester, e.g. polybutylene terephthalate and filler depending on occasion at the temperature range of -5 deg.C to -100 deg.C of PAS resin melting point, for example, at 260 deg.C for one hour or longer. Thus the heat resistance such as thermal deformation temperature can be improved by 10 deg.C or higher. |
