PROBLEM TO BE SOLVED: To obtain a thermoplastic resin compsn. which is excellent in moldability, mechanical properties, moisture resistance, molded appearance, and flame retardance by compounding a rubber-reinforced styrene resin, a polyamide resin, ammonium polyphosphate, and a flaky inorg. filler in a specified ratio. SOLUTION: One hundred pts.wt. compsn. comprising 95-10 wt.% rubber- reinforced styrene resin and 5-90 wt.% polyamide resin is compounded with 10-40 pts.wt. ammonium polyphosphate and 1-35 pts.wt. flaky inorg. filler. ABS, AES, AAS, and HIPS are listed as the rubber-reinforced styrene resin. Pref., the polyamide resin is nylon 6, nylon 46, nylon 66, nylon 6/6T, or the like. Commercially available ammonium polyphosphate can be used, and the one coated or microcapsuled with a thermosetting resin can also be used. Examples of the flaky inorg. filler are talc, mica, and glass flakes.
