Abstract
The present invention relates to a polymer composition comprising polyphenylene sulphide (PPS), polyamide 6 (PA6), reinforcing agents, wherein the weight ratio of PPS/PA6 is at least 2, with the proviso that the composition does not comprise an elastomer or comprises an elastomer in an amount not exceeding 1 wt. %. 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.
