ABSTRACT:
There is provided in accordance with the present invention polyphenylene ether/polyalkyleneterephthalamide compositions of high dimensional stabilities that are suitable for high temeprature applications comprising from about 20 to about 70 weight % of a functionalized polyphenylene ether; from about 20 to about 70 weight % of a polyalkyleneterephthalamide, wherein the polyalkyleneterephthalamide is derived from terephthalic acid and an .alpha.,.omega.-alkanediamine having 10 to 14 methylene groups; and from about 0 to about 20 weight % of a functionalized elastomeric polymer, wherein the blend absorbs less than 2 wt % of moisture and has a dimensional growth in water of less than 0.5%.
