Method for producing thermoplastic resin composition, thermoplastic resin composition and copier/printer exterior part
A method for producing a thermoplastic resin composition includes melt-blending 50 to 80 parts by mass of a crystalline polyester resin and 20 to 50 parts by mass of an amorphous polyester resin with an extruder, thereby producing a first polyester resin compound. The method further includes melt-blending 90 to 99 parts by mass of the crystalline polyester resin and 1 to 10 parts by mass of a styrene-acrylonitrile-glycidyl methacrylate terpolymer with the extruder or a different extruder, thereby producing a second polyester resin compound. The method further includes compounding 1 to 10 parts by mass of the first polyester resin compound, 1 to 10 parts by mass of the second polyester resin compound, and respective predetermined amounts of a polycarbonate resin, a flame retardant, an antidrip agent, an antioxidant, a lubricant and a toughening agent.
