摘要:
A thermoset composition exhibiting reduced water absorption in the cured state includes an olefinically unsaturated monomer and a capped poly(arylene ether) prepared by the reaction of an uncapped poly(arylene ether) with an anhydride capping agent. The capped poly(arylene ether) is isolated and/or purified by methods that reduce the concentrations of polar impurities that contribute to water absorption by the cured composition.

摘要:
A curable composition includes a functionalized poly(arylene ether) resin, an acryloyl monomer, and a phosphorus flame retardant. The composition exhibits an improved balance of properties such as toughness, flame retardance, heat-resistance, and moisture resistance. It is useful, for example, as an encapsulant for semiconductor products.
