Abstract: A foamed material includes 50 to 90 weight percent of a semicrystalline resin and 10 to 50 weight percent of a poly(phenylene ether). The semicrystalline resin can be one or more of a polyamide, a polyester, and a polyolefin. The foamed material has a density of 40 to 700 kilograms/meter3. It can be prepared by adding a blowing agent to a molten thermoplastic material containing the semicrystalline resin and the poly(phenylene ether), thereby forming a pre-foamed molten thermoplastic material, and extruding the pre-foamed molten thermoplastic material to form the foamed material. The foamed material is useful to form articles requiring solvent resistance.

Abstract: A foamed material includes specific amounts of a polystyrene, an organophosphate ester, and a poly(phenylene ether) or a poly(phenylene ether)-polysiloxane block copolymer or a combination thereof. The material is foamed with a C3-C5 alkane blowing agent. The foamed material is useful as insulation in the construction of walls and ceilings.

Abstract: A molding composition is disclosed which contains specific amounts of poly(arylene ether), styrenic polymer, hydrogenated block copolymer, flame retardant, and polytetrafluoroethylene. The molding composition performs well on a battery of tests, including heat resistance, impact strength, melt flow, and flame retardancy, and is particularly useful for producing photovoltaic junction boxes and connectors.

Abstract: The invention relates to methods of capping poly(phenylene ether) resin having an intrinsic viscosity between 0.05 and 0.35 dl/g. More particularly, the methods comprise capping a poly(phenylene ether) resin having an intrinsic viscosity between 0.05 and 0.35 dl/g in a solvent to produce a capped poly(phenylene ether) resin having an intrinsic viscosity between 0.05 and 0.35 dl/g and isolating the capped poly(phenylene ether) resin by removal of the solvent, preferably in a process other than precipitation. The invention also relates to the capped poly(phenylene ether) resin having an intrinsic viscosity between 0.05 and 0.35 dl/g.

Abstract: The present invention relates to flame retardant compositions of compatibilized polyphenylene ether-polyamide resin blends containing at least one phosphoramide compound. The present invention also relates to articles made from the resin compositions as well as methods to make flame retardant compositions of compatibilized polyphenylene ether-polyamide resin blends.
