POLYPHENYLENE ETHER-BASED RESIN COMPOSITION AND MOLDED ARTICLE
A polyphenylene ether-based resin composition includes 25 to 84 mass % of a polyphenylene ether (A), 1 to 20 mass % of a styrene-based thermoplastic elastomer (B), 4 to 25 mass % of a flame retardant (C), and 11 to 30 mass % of a kaolin clay (D) when a total content of these four components is taken as 100 mass %. The (C) component contains, per 100 mass % of the (C) component, 0 to 97 mass % of an organophosphorus flame retardant (C-1) having a 10-mass % reduction temperature 380 to 430° C., and 100 to 3 mass % of an organophosphorus flame retardant (C-2) having a 10-mass % reduction temperature 330 to 360° C. The 10-mass % reduction temperature is determined from a heating loss curve obtained by heating about 10 mg of the (C-1) or (C-2) component from 30° C. to 800° C. at 10° C./min under a nitrogen atmosphere in a TGA measurement apparatus.

Method for preparing a poly(phenylene ether) and poly(phenylene ether) prepared thereby
A method for preparing a poly(phenylene ether) includes feeding air to a continuous flow reactor that contains a reaction mixture including a phenol, a transition metal catalyst, and an organic solvent; and oxidatively polymerizing the reaction mixture at a specified temperature and pressure to form a poly(phenylene ether). The reaction mixture has a residence time in the continuous flow reactor of less than or equal to 30 minutes. Poly(phenylene ether)s prepared by the method and articles including the poly(phenylene ether)s are also described.
