Abstract:
An injection moldable composition comprising(a) a high temperature, partially aromatic polyamide comprising aliphatic diamine terephthalamide units represented by the following structural formula: â€ƒwherein R comprises at least one C2-C14 aliphatic hydrocarbyl radical; (b) an olefinic impact modifier; (c) from 0.01 to about 2 wt. %, based on total weight of the composition, of a copper-containing thermal stabilizer formulation comprising an alkali metal halide and a copper (I) halide in a weight ratio of from about 2.5:1 to about 20:1; and (d) from 0.01 to about 3 wt. %, based on total weight of the composition, of at least one compound selected from secondary aryl amines and hindered phenols, wherein said compound has a molecular weight of at least 260 g/m and a 10% wt. loss temperature of at least 290Â° C., as determined by TGA according to ASTM D 3850-94.
