A composition containing a solvent and a soluble poly(arylene ether) copolymer is described. The poly(arylene ether) copolymer is the product of oxidative polymerization of monomers including a first monohydric phenol having identical substituents in the 2- and 6-positions, and a second monohydric phenol comprising ethylenic unsaturation and having different substituents in the 2- and 6-positions. The solvent may be a ketone, a dialkylamide, a dialkyl ether, an aromatic hydrocarbon, a chlorinated hydrocarbon, an alkyl alkanoate, an alkyl cyanide, a dialkyl sulfoxides, or a mixture thereof. The poly(arylene ether) has a solubility in the composition of at least 10 grams per kilogram of composition at 25° C.
