Title (EN) USE OF POLYAMIDE 6 (PA6) AS A HEAT-AGING STABILIZER IN POLYMER COMPOSITIONS COMPRISING POLYPHENYLENE SULFIDE (PPS)
(FR) UTILISATION DE POLYAMIDE 6 (PA6) EN TANT QUE STABILISATEUR DE VIEILLISSEMENT THERMIQUE DANS DES COMPOSITIONS POLYMÈRES COMPRENANT DU SULFURE DE POLYPHÉNYLÈNE (PPS)
Abstract:
(EN) 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.
(FR) La présente invention concerne une composition polymère comprenant du sulfure de polyphénylène (PPS), du polyamide 6 (PA6), des agents de renforcement, le rapport pondéral de PPS/PA6 étant d'au moins 2, à condition que la composition ne comprenne pas d'élastomère ou comprenne un élastomère en une proportion ne dépassant pas 1 % en poids. La présente invention concerne également des articles incorporant la composition polymère et l'utilisation de polyamide 6 (PA6) en tant que stabilisateur de vieillissement thermique dans une composition polymère.
