| abstract |
A shaped wholly aromatic polyamide resin composition article having an excellent mechanical strength, stain-proof property and antistatic property, and comprising a wholly aromatic polyamide resin matrix and a dispersoid comprising polytetrafluoroethylene resin particles in the form of fine networks of fibrils and, optionally, additional inorganic particles, dispersed in the matrix, is produced by mixing an aqueous dispersion of PTFE particles having an average size of 0.3 to 3 mu m in an amount of 0.01% to 10% based on the total weight of the shaped article, with wholly aromatic polyamide particles having a melting point of at least 50 DEG C. higher than that of PTFE and composed of porous secondary particles having an average size of 30 to 200 mu m and consisting of primary particles having an average size of 0.1 to 2.0 mu m; drying the mixture to provide composite particles composed of aromatic polyamide cores and PTFE coating layers on the cores; and shaping a feed powder comprising the composite particles at a temperature not lower than the glass-transition point but not lower than the melting point or heat decomposition point of the aromatic polyamide, under a pressure. |
