Abstract
A curable composition includes a functionalized poly(arylene ether), a vinyl thermoset resin, and a flame retardant composition. The flame retardant composition includes a trihydrocarbylphosphine oxide and a nitrogen-containing flame retardant that may be melamine phosphate, melamine pyrophosphate, or melamine polyphosphate. The combination of the trihydrocarbylphosphine oxide and the nitrogen-containing flame retardant is particularly effective at improving the flame retardancy of the cured composition at relatively low levels of total flame retardant. A method of preparing the curable composition and articles including the cured composition are also described.
