ABSTRACT OF THE DISCLOSURE Polyphenylene ether resins with narrow particle size distribution, higher bulk density, and of substantially lower content of dusty, fine particles are obtained by precipitation from their solution in an organic aromatic solvent with a non- solvent medium which is capable of forming a two-phase system with the aromatic solvent. In especially preferred embodi- ments, the polyphenylene ethers assume spheriodal shape during precipitation. The improved form of polyphenylene ethers facilitates bagging, transfer and compounding, and improves the appearance and physical properties of articles molded therefrom.
