Abstract: A process for producing a modified polyphenylene ether resin having a purity of more than 99.4%, comprising steps of graft modification, water rinse, and extraction as well as phase splitting, is disclosed that step of separating out powder during purification is no needed, and the solvent for use in performing dissolving of or/and extraction of polyphenylene ether resin can be recycled for future use, so that the manufacturing process is simple and uses less solvent as compared to the prior art, and further helps to conserve resources and is environmentally friendly.
