1. A method of making a composition comprises:
melt mixing a first mixture comprising a poly(arylene ether) and a compatibilizing agent to form a first melt mixture;
melt mixing a second mixture comprising the first melt mixture and a polyamide, electrically conductive additive and a flame retardant masterbatch wherein the flame retardant masterbatch comprises a phosphinate and a thermoplastic resin, wherein the flame retardant masterbatch comprises 20-80 weight percent phosphinate and 20-80 weight percent thermoplastic resin with respect to the combined weight of phosphinate and thermoplastic resin.
