  • Process for the manufacture of functionalized polyphenylene ether resins
    Patent number: 6417274
    Abstract: The invention relates to a novel process for preparing functionalized PPE, the process comprising oxidative coupling in a reaction solution at least one monovalent phenol species using an oxygen containing gas and a complex metal catalyst to produce a PPE; and functionalizing the PPE prior to and/or during at least one isolation step for devolatilization of the reaction solvent. The invention also relates to the polyphenylene ether resin made by the process as well as blends and articles containing the polyphenylene ether resin made by the process.
