A method for preparing a poly(phenylene ether) includes feeding an oxygen-containing gas phase to a single continuous flow reactor containing a reaction mixture, and oxidatively polymerizing the reaction mixture to form a poly(phenylene ether) in the single reactor. The reaction mixture includes a phenol, a transition metal catalyst, and an organic solvent. A poly(phenylene ether) made by the method and articles including the poly(phenylene ether) are also disclosed. Methods for quantifying phenol concentration and poly(phenylene ether) molecular weight in the reaction mixture are also discussed.

Method of preparing a poly (phenylene ether), poly(phenylene ether) made thereby, and article comprising the poly(phenylene ether)

A dielectric polymeric composition comprising a polymeric matrix comprising structural units derived from a polymerizable vinyl monomer; an ionic liquid comprising an organic cation and a balancing anion, wherein the ionic liquid is miscible or partially miscible with the polymerizable vinyl monomer, and wherein the concentration of ionic liquid in dielectric polymeric composition ranges from 0.5 to 30 wt. %; and less than 10 ppm of unreacted polymerizable vinyl monomer, based on the total weight of the composition, wherein an amount of unreacted polymerizable vinyl monomer in the composition is measured via HPLC. The polymeric matrix further comprises structural units derived from a polymerizable co-monomer comprising a functional group that has the ability to form hydrogen bonds within the polymeric matrix. The polymeric matrix further comprises a crosslinking agent, and wherein the polymeric matrix comprises covalent crosslinks between the crosslinking agent and the structural units derived from the polymerizable vinyl monomer.
