    摘要: A poly(arylene ether) copolymer is the product of oxidative copolymerization of monomers including a monohydric phenol and a dihydric phenol. It has an intrinsic viscosity of about 0.04 to about 0.15 deciliter per gram and, on average, about 1.8 to about 2 hydroxyl groups per molecule. The poly(arylene ether) copolymer is enriched in low molecular weight copolymer chains and copolymer chains that include a terminal unit derived from the dihydric phenol.

    摘要: A composition includes at least 15 weight percent of a low intrinsic viscosity, bifunctional poly(arylene ether) and at least 20 weight percent of a nonhalogenated solvent. The bifunctional poly(arylene ether)s are substantially and unexpectedly more soluble than their monofunctional analogs. The compositions are useful as concentrates to add bifunctional poly(arylene ether)s to thermosets.

    摘要: A poly(arylene ether) may be fractionated into higher and lower molecular weight fractions by forming a mixture that includes a poly(arylene ether) starting material, a first solvent that is dichloromethane, bromochloromethane, dibromomethane, or a mixture thereof, and a second solvent different from the first solvent having a Hildebrand solubility parameter of about 16 to about 22 megapascal1/2. The mixture separates into fractions containing higher and lower molecular weight poly(arylene ether)s.

    摘要: The invention relates to a method of forming a polyphenylene ether resin containing residual aliphatic unsaturation. A polyphenylene ether is reacted with a capping agent in a solvent to form the polyphenylene ether resin containing residual aliphatic unsaturation, which is precipitated from solution by combining the solution with an antisolvent. The precipitated polyphenylene ether resin containing residual aliphatic unsaturation has lower levels of residual impurities than the same compound isolated by devolatilization.

    摘要: A curable composition includes an epoxy resin and a bifunctional poly(arylene ether) having an intrinsic viscosity of about 0.03 to about 0.2 deciliter per gram. After curing, the composition exhibits markedly improved impact strength relative to a corresponding composition prepared from monofunctional poly(arylene ether).

    摘要: A curable composition includes an alkyl styrene and a low molecular weight, bifunctional poly(arylene ether). The composition can be prepared and processed at substantially lower temperatures than prior art poly(arylene ether) thermosets. After curing, the composition exhibits an improved balance of heat resistance, impact strength, and dielectric properties, making it particularly suitable for the fabrication of electronic components.
