Abstract: A phenylene ether oligomer composition is disclosed comprising, a phenylene ether oligomer having an external amine content of less than or equal to 1.5 weight percent; and a residual solvent in an amount of 10 to 10000 parts per million by weight, based on the weight of the phenylene ether oligomer composition; wherein the phenylene ether oligomer composition has an intrinsic viscosity of 0.03 to 0.13 deciliter per gram; a glass transition temperature of 135 to 175° C., or a combination thereof.
