Abstract: PROBLEM TO BE SOLVED: To obtain a nylon resin composition excellent in electric properties such as tracking resistance, having excellent flame resistance, mechanical properties, heat resistance and moldability, and useful as an electric part, an electronic part, an automobile electric or electronic part or the like by compounding a nylon resin, a brominated flame retardant, an antimony compound, magnesium hydroxide and glass fiber. SOLUTION: This composition is obtained by compounding (A) a nylon resin (e.g. nylon 6) preferably in an amount of 100 pts.wt. with (B) 5-50 pts.wt. of a brominated flame retardant (e.g. polydibromostyrene), (C) 2-15 pts.wt. of an anitomony compound (e.g. antimony trioxide), (D) 20-50 pts.wt. of magnesium hydroxide and (E) 10-100 pts.wt. of glass fiber, and preferably further, (F) 0.01-5 pts.wt. of a fluororesin and (G) 0.01-3 pts.wt. of a hindered phenol-based stabilizer. The bromine content of the component B is preferably >=60 wt.%. Further, the aspect ratio of the component E is preferably 15-45.

Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a thermoplastic resin composition, capable of preventing the scattering of an additive to the outside of a solid phase polymerization vessel accompanying with the decrease of pressure in the solid phase polymerization. SOLUTION: This method for producing the thermoplastic resin composition is characterized in that a tablet-formed additive is used in one or a plural number of additives used in a rotary batch type solid phase polymerization device under a reduced pressure, also among the composition of the additives, the melting point of at least one of them is at or less than the temperature for the solid phase polymerization, the ratio of the diameter to height of the tablet-formed additive is 0.5-2.5 and also the breaking strength of the tablet-formed additive is 3-15 kg.
