摘要： The present disclosure provides a polyphenylene ether composition having a high glass transition temperature and a long-term solubility in a solvent, and exhibiting a low viscosity when being dissolved in a solvent. The polyphenylene ether composition of the present disclosure contains 60 mol% or more of a polyphenylene ether having the structure of Formula (1), wherein the ratio of the integrated value of the peak appearing at 7.6 to 8.3 ppm to the integrated value of the peak derived from the structure of the following Formula (2) in a 1 H-NMR measurement result is 1 or less, and the number average molecular weight in terms of polystyrene is 500 to 15,000 g/mol.
