METHOD OF MANUFACTURING POLYPHENYLENE OXIDE, POLYPHENYLENE OXIDE RESIN COMPOSITION, PREPREG, LAMINATE, PRINTED WIRING BOARD AND MULTILAYERED PRINTED WIRING BOARD

摘要

PROBLEM TO BE SOLVED: To provide a method of manufacturing a polyphenylene oxide capable of improving moldability when molded and reducing a dielectric constant and a dielectric loss tangent of a cured molded article. SOLUTION: The molecular weight of a polyphenylene oxide is reduced by reacting it with a monofunctional phenol. The polyphenylene oxide having the reduced molecular weight obtained by a decomposition and rearrangement reaction has low polarity and a low dielectric constant and can be used favorably as a molding material for a laminate having a reduced dielectric constant.
