Abstract:
1. An article comprising a composition comprising the product of melt blending components comprising, based on the total weight of blended components: 44 to 74.9 weight percent poly(phenylene ether); 15 to 30 weight percent of a radial block copolymer of an alkenyl aromatic monomer and a conjugated diene; wherein the radial block copolymer comprises 60 to 70 weight percent of poly(alkenyl aromatic) content based on the weight of the radial block copolymer, and has a number average molecular weight of 50,000 to 70,000 atomic mass units; 7.5 to 15 weight percent of a polystyrene-poly(ethylene-butylene)-polystyrene triblock copolymer having a polystyrene content of 55 to 80 weight percent based on the weight of the triblock copolymer; 2.5 to 7.5 weight percent of a hydrogenated terpene resin having a softening point of 145 to 155° C. measured according to ASTM E28; and 0.1 to 2 weight percent of a hydroxy compound selected from the group consisting of hydroxyacetone, acetoin, allyl alcohol, pinacol, 2,3-diphenylbutane-2,3-diol, 2-butene-1,4-diol, benzyl alcohol, 1-phenylethanol, 2-hydroxyacetophenone, benzopinacol, benzoin, hydrobenzoin, 2-hydroxy-1-phenyl-2-p-tolyl-ethanone, benzhydrol, and combinations thereof; wherein the composition excludes flame retardants other than compounds approved for use as food additives by the United States Food and Drug Administration as of Oct. 31, 2006; and wherein the composition comprises less than 0.01 weight percent of trihydrocarbyl phosphites.
