The present invention relates to a melt blended composition of the reaction product of about 70 to 99.99 percent by weight polyphenylene oxide, and about 0.01 to 30 percent by weight of a substituted olefin having the formula: <IMAGE> wherein one to two of R1, R2, R3 and R4 are moieties containing reactive groups selected from carboxylic acid, acid anhydride, acid amide, imido, carboxylic ester, amino, hydroxyl, epoxy, group, oxazoline, oxazolone, oxazine, oxazinone, isocyanate, carbamate, carbamoyl lactam, acyl lactam, and mixtures and derivatives thereof, and wherein the remaining two to three of R1, R2, R3 and R4 are H or a hydrocarbon radical of from 1 to about 20 carbon atoms; and polyolefin. The present invention also relates to a blended composition of the foregoing reaction product; thermoplastic polymer; and a functionalized ethylene alpha -olefin rubber. The melt blended composition has good impact resistance.
