ABSTRACT:
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.
