PURPOSE:To provide the resin composition excellent in the balance of flowability, heat resistance and mechanical characteristics and not causing the melt-dropping of the resin on combustion by adding a phosphorus compound and a phenol novolak resin to the polyphenylene ether resin. CONSTITUTION:(A) 100 pts.wt. of a polyphenylene ether resin, (B) 0.1-30 pts.wt. of a phosphorus compound (e.g. triphenylphosphate) such as a phosphate ester compound of formula I (Q is divalent residue such as 2-14C aliphatic hydrocarbon residue, 6-20C aryl, aralkyl, etc.; Q1-Q4 are H, 1-6C alkyl; n is an integer of >=1; m1-m4 are an integer of 1-3), formula II, etc., and (C) 0.05-5 pts.wt. of a phenol novolak resin are compounded to obtain the flame-resistant polyphenylene ether resin composition excellent in the balance of flowability, heat resistance, mechanical characteristics, etc., and not causing the melt- dropping of the resin on combustion. |
