摘要：
The structure of poly(oxy-2,dimethyl-1,4-phenylene) (PPE) was studied by H-1 NMR spectroscopic analysis. Several compounds were prepared in order to compare their NMR spectra to PPE's. The structure of PPE was composed of a unit of 2,6-dimethylphenol (DMP) which is synthesized by the head-to-tail polymerization. The structure made by branched reaction or Fries-type rearrangement was not observed. Dibutylamino groups were recognized in the polymer structure and their H-1 NMR signals were observed in the range of 1.3 ppm to 2.3 ppm. The amine structure was introduced into the polymer at the polymerization.
