    • 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 ##STR1## wherein the --CO-- and --S-- are in the para position to each other, and has a melting point, Tm of 310.degree.-380.degree. C., a residual melt cyrstallization enthalpy, .DELTA.Hmc (420.degree. C./10 min) of at least 10 J/g, a melt crystallization temperature, Tmc (420.degree. C./10 min) of at least 210.degree. C., and a reduced viscosity of 0.2-2 dl/g as determined by viscosity measurement at 25.degree. 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.
