ABSTRACT:
A moldable thermosetting composition comprises a poly(arylene ether), a thermosetting resin, a toughening agent, and an amine cure agent. The compositions may be conveniently prepared without solvents, and the poly(arylene ether) may be provided in the form of an easily dissolved solid concentrate with the thermosetting resin.
