Procedure

1.0 kg of ε-caprolactam, 3.0 kg of 12-aminododecanoic acid and 200 g of fluoromica (average particle size 8 μm, CEC corresponding to 0.14 mole) were added to 1.5 kg of water. Into a 30 L volume reactor which was in advance charged with 4 kg of ε-caprolactam were introduced the above-described mixture and 16.1 g (0.14 mole) of 85 wt % phosphoric acid aqueous solution. The pellets of nylon 6/12 resin composition were prepared in the same manner as in Comparative Example 3. After being refined in 95° C. hot water and dried, the pellets were injection molded in an injection molding machine (IS80G-3A Model, manufactured by Toshiba Machine, Ltd.) at a cylinder temperature of 250° C. and a mold temperature of 50° C. for an injection time of 6 seconds and a cooling time of 10 seconds to prepare 2 mm thick plates and 3.2 mm thick specimens for testing.
