Patent ID: 8445573

Claim:
A polyphenylene ether resin composition obtainable by melt-mixing a polyphenylene ether (A) comprising a structural unit (a) represented by the following formula (1): wherein R 1 and R 2 each independently represent a hydrogen atom, a halogen atom, an optionally substituted alkyl group, an optionally substituted alkoxy group, an optionally substituted aryl group, an optionally substituted aryloxy group, an optionally substituted aralkyl group or an optionally substituted aralkyloxy group, and/or a structural unit (b) represented by the following formula (2): wherein R 3 and R 4 each independently represent a hydrogen atom, a halogen atom, an optionally substituted alkyl group, an optionally substituted alkoxy group, an optionally substituted aryl group, an optionally substituted aryloxy group, an optionally substituted aralkyl group or an optionally substituted aralkyloxy group, and R 5 represents a halogen atom, an optionally substituted alkyl group, an optionally substituted alkoxy group, an optionally substituted aryl group, an optionally substituted aryloxy group, an optionally substituted aralkyl group or an optionally substituted aralkyloxy group, with a nitrogen compound (B) comprising at least three groups selected from the group consisting of primary amino groups, secondary amino groups, and tertiary amino groups in a single molecule thereof, wherein the polyphenylene ether (A) comprises 0.1% by mass or more and 1.5% by mass or less of at least one type of aromatic hydrocarbon (C) containing 7 or 8 carbon atoms, the primary amino groups, the secondary amino groups, and the tertiary amino groups are each contained in an amount of 0.1% by mole or more in the nitrogen compound (B), and a molecular weight of the nitrogen compound (B) is 200 or more.
