Abstract
Disclosed is a stabilized polyphenylene ether resin which comprises a plurality of polyphenylene ether chains, which chains collectively contain terminal 6-chroman groups in an amount of at least 0.01 in terms of the number of the terminal 6-chroman groups per 100 polyphenylene ether units in the resin. This polyphenylene ether resin has excellent resistance to thermal oxidation. A composition comprising this stabilized polyphenylene ether resin and a polystyrene resin has not only high resistance to thermal oxidation but also excellent moldability.
