- 65 - ABSTRACT Disclosed herein is a melt-stable poly(arylene thioether-ketone) composition, which comprises: (A) 100 parts by weight of a melt-stable poly(arylene thioether-ketone) having predominant recurring units of the formula Image and having a melting point, Tm of 310-380°C, a residual melt crystallization enthalpy, .DELTA.Hmc (420°C/10 min) of at least 10 J/g, a melt crystallization temperature, Tmc (420°C/10 min) of at least 210°C and a reduced viscosity of 0.2-2 d?/g; (B) 0-400 parts by weight of at least one of thermoplastic resins; and (C) at least one of fibrous fillers and/or at least one of inorganic fillers in a proportion of 0-400 parts by weight per 100 parts by weight of the sum of said components (A) and (B). At least either one of the components (B) or (C) is contained in a proportion of at least 0.1 part by weight per 100 parts by weight of the component (A).
