Abstract
Stabilized polyphenylene ether type resin composition obtained by compounding a polyphenylene ether type resin with one or more of stabilizer-component such as those respectively (a) a high molecular phosphorous ester having at least three phosphorous ester-bondings per molecule, (b) a high molecular phosphorous ester as said above and dicarboxylic acid dihydrazide substitution product, (c) a high molecular phosphorous ester as said above and steric hindered phenols and (d) a high molecular phosphorous ester as said above, steric hindered phenols and dicarboxylic acid dihydrazide substitution product; and, if desired, boron oxide.
