METHOD OF PREPARING A POLY(PHENYLENE ETHER), POLY(PHENYLENE ETHER) MADE THEREBY, AND ARTICLE COMPRISING THE POLY(PHENYLENE ETHER)

摘要

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.
