ABSTRACT:
A 2,6-dimethylphenol composition having an m-cresol content of from 15 to 700 ppm on a weight basis has effects of drastically improving polymerization activity and particularly, improving the color tone of polyphenylene ethers. Therefore, the composition makes it possible to provide a preparation process having improved productivity, and at the same time, provide polyphenylene ethers having good quality.
