The oxidation of Ix)ly ( 2,6-dimethyl-C, 4-phenylene ether) (PPE) during polymerization has been examined as a function of molecular weight, using spectroscopic techniques. The visible light absorption and the IR absorption at 1660cm -I increased as the molecular weight decreased. A most probable ch
