  • Process for the manufacture of low molecular weight polyphenylene ether resins
    Patent number: 6437085
    Abstract: The invention relates to a novel process for the manufacture of very low molecular weight polyphenylene ether resin, typically within the intrinsic viscosity range of about 0.08 dl/g to about 0.16 dl/g as measured in chloroform at 25° C. The method preferably comprises 2,6-dimethylphenol as a monovalent phenol species. 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.
    Type: Grant
    Filed: October 2, 2001
    Date of Patent: August 20, 2002
    Assignee: General Electric Company
    Inventors: Adrianus J. F. M. Braat, Hugh Ingelbrecht, Ruud Trion
