PROBLEM TO BE SOLVED: To obtain the subject composition capable of providing self- extinguishable a molding product having excellent flame retardance in terms of drip, and extremely superior in thermal stability, molding processability, and falling weight impact resistance of a thin-wall product. SOLUTION: This composition is obtained by compounding (A) 100 pts.wt. rubber-reinforced styrenic resin, (B) 1-30 pts.wt. organic phosphorus compound of formula I [X is an arylene; R<1> to R<4> are each a (substituted) phenyl], (C) 0.1-20 pts.wt. mixture of (i) 1-40 wt.% salt of a compound of formula II (R<6> to R<9> are each H, an aryl, an alkyl, etc.; R<5> is NR<6> R<7> , NR<8> R<9> , etc.), and cyanuric acid or isocyanuric acid with (ii) 99-60 wt.% polyamide resin. Preferably, the component C is previlusly melted and kneaded at 190-300 deg.C. |
