  • CURABLE POLY(ARYLENE ETHER) COMPOSITION AND METHOD
    Publication number: 20080071035
    Abstract: 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).

  • CURED POLY(ARYLENE ETHER) COMPOSITION, METHOD, AND ARTICLE
    Publication number: 20080071036
    Abstract: A cured composition is prepared by curing a curable composition including an epoxy resin and a bifunctional poly(arylene ether) having an intrinsic viscosity of about 0.03 to about 0.2 deciliter per gram. The cured composition exhibits markedly improved impact strength relative to a corresponding composition prepared from monofunctional poly(arylene ether).

  • POLY(ARYLENE ETHER) PROCESS AND COMPOSITION
    Publication number: 20070299243
    Abstract: A method of purifying a polymerization reaction mixture containing a poly(arylene ether) is described. The method uses multiple separations of organic and aqueous phases to achieve rapid and efficient removal of polymerization catalyst metal from the poly(arylene ether). When combined with particular precipitation conditions, the method produces a poly(arylene ether) having an improved combination of particle size distribution and low catalyst metal concentration.
