Method for preparing a poly(phenylene ether) and poly(phenylene ether) prepared thereby |
| abstract |
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. |
