Abstract
The present invention relates to a polymer composition (C) comprising: —a polyphenylene sulfide (PPS), —at least 3 wt. % of polyamide 6 (PA6), —25 to 60 wt. % of reinforcing agents, —3 to 8 wt. % of a functionalized, non-aromatic elastomer, wherein the weight ratio PPS/PA6 is at least 4 and wherein wt. % are based on the total weight of the composition. The present invention also relates to articles incorporating the polymer composition and the use of polyamide 6 (PA6) as a heat-aging stabilizer in a polymer composition.
