PURPOSE:A composition obtained by blending a mixture of a polyphenylene ether resin and a styrenic resin with an ammonium halide, having extremely improved flame retardance without damaging properties of both the resins. CONSTITUTION:100pts.wt. polymer composition consisting of a polyphenylene ether resin and a styrenic resin is blended with 0.05-15pts.wt., preferably 0.1- 10pts.wt. ammonium halide. Poly(2,6-dimethylene-1,4-phenylene)ether, or a copolymer of 2,6-dimethylphenol and 2,3,6-trimethylphenol is used as the polyphenylene ether resin, and rubber midified polystyrene having high impact resistance, or styrene/acrylonitrile/butadiene terpolymer as the styrenic resin. Ammonium bormide or ammonium chloride is preferable as the ammonium halide. |
