Disclosed herein is a molded or formed poly(arylene thioether-ketone) article made of a thermoplastic material which comprises 100 parts by weight of a melt-stable poly(arylene thioether-ketone) (PTK) and if desired, up to 100 parts by weight of at least one of thermoplastic resins and/or up to 300 parts by weight of at least one of fibrous fillers and/or least one of inorganic fillers. The PTK has predominant recurring units of the formula <IMAGE> wherein the -CO- and -S- are in the para position to each other, and has a melting point, Tm of 310 DEG -380 DEG C., a residual melt cyrstallization enthalpy, DELTA Hmc (420 DEG C./10 min) of at least 10 J/g, a melt crystallization temperature, Tmc (420 DEG C./10 min) of at least 210 DEG C., and a reduced viscosity of 0.2-2 dl/g as determined by viscosity measurement at 25 DEG C. and a polymer concentration of 0.5 g/dl in 98 percent by weight sulfuric acid. This invention provides extruded articles, injection-molded articles, unstretched films and the like, all of which have practical physical properties, by using a novel high-density and high crystallinity PTK having melt stability sufficient to apply conventional melt processing techniques.
