Phenylene ether oligomer composition

A phenylene ether oligomer composition comprising,

• a phenylene ether oligomer having an external amine content of greater than 0 to less than or equal to 1.3 weight percent;
• and
• wherein the phenylene ether oligomer composition has a residual solvent in an amount of 10 to 10,000 parts per million by weight, based on the weight of the phenylene ether oligomer composition;
• wherein the external amine has a formula
• wherein:
• Z1 is halogen, unsubstituted or substituted C1-C12 hydrocarbyl provided that the hydrocarbyl group is not tertiary hydrocarbyl, C1-C12 hydrocarbylthio, C1-C12 hydrocarbyloxy, or C2-C12 halohydrocarbyloxy wherein at least two carbon atoms separate the halogen and oxygen atoms;
• each occurrence of Z2 is independently hydrogen, halogen, unsubstituted or substituted C1-C12 hydrocarbyl provided that the hydrocarbyl group is not tertiary hydrocarbyl, C1-C12 hydrocarbylthio, C1-C12 hydrocarbyloxy, or C2-C12 halohydrocarbyloxy wherein at least two carbon atoms separate the halogen and oxygen atoms;
• each occurrence of R1 is independently hydrogen or unsubstituted or substituted C1-C12 hydrocarbyl;
• and
• each occurrence of R2 is independently an unsubstituted or substituted C1-C12 hydrocarbyl;
• 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.
