    摘要: A flame retardant poly(arylene ether) composition is described. In addition to the poly(arylene ether), the composition includes a polyolefin component, and a flame retardant composition that includes a metal dialkyl phosphinate and a nitrogen-containing flame retardant but excludes a liquid triaryl phosphate. The polyolefin component can be a polyolefin polymer and/or the polyolefin block of a poly(alkenyl aromatic)-polyolefin block copolymer. The composition is particularly suitable as a replacement for poly(vinyl chloride) in insulation for wire and cable.

    摘要: A poly(arylene ether) composition includes a hydrogenated block copolymer of an alkenyl aromatic compound and a conjugated diene, a flame retardant, and a poly(arylene ether)-polysiloxane block copolymer reaction product that itself includes a poly(arylene ether)-polysiloxane block copolymer. The composition is useful for forming extruded articles, including insulation for wire and cable. The poly(arylene ether)-polysiloxane block copolymer contributes improved flame retardancy and, in many cases, improved physical properties to the composition.

    摘要: A composition is prepared by oxidative copolymerization of specific amounts of 2,6-dimethylphenol, 2,3,6-trimethylphenol, and a hydroxyaryl-terminated polysiloxane. The composition exhibits an increased heat resistance relative to a corresponding composition prepared by copolymerizing 2,6-dimethylphenol and hydroxyaryl-terminated polysiloxane, without 2,3,6-trimethylphenol. The composition is useful as a flame-retardant additive in polymer compositions that require high heat resistance.

    摘要: A thermoplastic composition that includes a poly(arylene ether)-polysiloxane block copolymer is prepared by a method that includes oxidatively copolymerizing a monohydric phenol and a hydroxyaryl-terminated polysiloxane. The oxidative polymerization includes a monohydric phenol addition period characterized by a first temperature, a build period following the addition period and characterized by a second temperature greater than the first temperature, and a temperature ramp period between the addition period and the build period. During the temperature ramp period, the temperature is increased at an average rate of about 0.01 to about 0.35° C. per minute, which improves the efficiency with which the hydroxyaryl-terminated polysiloxane is incorporated into the poly(arylene ether)-polysiloxane block copolymer.
