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.

A method for preparing a poly(phenylene ether) includes feeding air to a continuous flow reactor that contains a reaction mixture including a phenol, a transition metal catalyst, and an organic solvent; and oxidatively polymerizing the reaction mixture at a specified temperature and pressure to form a poly(phenylene ether). The reaction mixture has a residence time in the continuous flow reactor of less than or equal to 30 minutes. Poly(phenylene ether)s prepared by the method and articles including the poly(phenylene ether)s are also described.

A method for carrying out a reaction between at least two reactants in a liquid reaction solution in at least one reaction zone so as to produce a reaction product includes carrying out a reaction continuously in a reaction flow for the at least one reaction zone in an extension of the at least one reaction zone as far as at least one reaction product outlet, introducing each of the at least two reactants over the extension of the at least one reaction zone via inlets in which the reaction flow is introduced, and removing the reaction product via the at least one reaction product outlet.
