PURPOSE:To obtain articles of improved releasability without impairing mechanical strength, thermal performance and appearance, by attaching a finely powdery specific releasing agent on the surface of pellets or powder of specific aromatic polyester resin. CONSTITUTION:The objective articles can be obtained by blending (A) either powder or pellets of an aromatic polyester resin of formula (R<1>-R<8> are each H, halogen or 1-10C hydrocarbon; X is 1-20C divalent hydrocarbon, O, S, SO etc.; a is 0 or 1) with a logarithmic viscosity 0.2-2.0 with (B) a metallic soap-based releasing agent (at least one sort of salt selected from Mg, Ca, Zn, and Ba salts) and/or fatty acid amide-based one (10-30C fatty acid amide) to attach 200-1,00 (pref. 300-700)ppm of said agent(s) on the surface of said power or pellets.
