The invention relates to a graft polymer composition based on acrylonitrile/ethylene-.alpha.-olefin-rubber/styrene, in particular, acrylonitrile/EPDM/styrene (AES) having an additive that increases, in a specified manner, the soft phase portion in the composition. Said graft polymer composition enables the production of shaped bodies that exhibit an improved strength at low temperatures, whereby the melt volume flow rate remains essentially unchanged due to the provision of said additive.
L'invention concerne une composition de polymère greffé à base d'acrylonitrile/éthylène-.alpha.-oléfine-caoutchouc/styrène, notamment de l'acrylonitrile/EPDM/styrène (AES) comprenant un additif augmentant de manière ciblée la part de phase molle dans la composition. L'utilisation de cette composition permet de produire des corps moulés à résistance renforcée dans la plage des basses températures, l'additif mentionné précédemment ne modifiant sensiblement pas le débit volumique de fusion.
