    摘要: A shaped electroconductive thermoplastic resin composition article having a preferable surface appearance is produced by a process including (1) mixing a matrix resinous material containing 100 parts by weight of a thermoplastic resin and, optionally, 120 parts by weight or less of a flame x retardant additive and 40 parts by weight or less of a flame retardant synergistic additive, with 1 to 15% based on the weight of the matrix resinous material, of stainless steel fibers having a length of 2.5 to 7.5 mm and adhered to each other with a thermoplastic resinous adhesive to form a number of bundles; (2) kneading the resultant mixture at an elevated temperature at which the matrix resinous material is melted and (3) shaping the kneaded mixture into a desired form, the kneading the shaping procedures being carried out so that the stainless steel fibers are uniformly dispersed in the melted matrix resinous material and the dispersed stainless steel fibers have an average length of 0.5 to 2.0 mm. The ratio of the average length of the dispersed and sheared stainless steel fibers to the length of the stainless steel fiber bundles is preferably in a range of 1/6 to 1/3.
