Patent abstract
A composition comprises an impact modifier 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 aliphatic-aromatic polyamide has a melt viscosity greater than or equal to 2000 Pa-s at a shear of 1000 second−1 and a temperature of 330° C. and the composition has a melt viscosity greater than or equal to 160 Pascal seconds (Pa-s) at a shear of 1500 second−1 (s−1) and a temperature of 330° C.
