Polymer compositions comprise a polyphenylene ether resin and a plasticizing compound of the formula
wherein X is selected from the group consisting CH₂, O and S; Y is different from X and is selected from the group consisting of CH₂, O, CO, S, SO and SO₂; Ar is an aromatic ring; Z¹ and Z² are individually selected from the group consisting of alkyl, alkoxide, aryl, aryl oxide, halogen, nitrile and nitro groups; R is hydrogen or an alkyl group; m is from 0 to 3; n is from 1 to about 10; and a and b are individually from 0 to 4; provided that both X and Y are not simultaneously oxygen. The compositions may further include a polystyrene resin, for example, a rubber-modified polystyrene resin.
