ABSTRACT:
A composition comprises greater than or equal to 20 weight percent glass fiber, based on the total weight of the composition, and a compatibilized blend of a poly(arylene ether) and an aliphatic-aromatic polyamide. The polyamide is composed of dicarboxylic acid units comprising 60 to 100 mol % of terephthalic acid units and diamine units comprising 60 to 100 mol % of 1,9-nonanediamine units and/or 2-methyl-1,8-octanediamine units. The polyamide has an amine end group content greater than 45 micromoles per gram of polyamide. The composition has a heat distortion temperature (HDT) greater than or equal to 230° C. when measured according to ASTM D 648 at 1.8 megapascals (MPa).
