An impact modified thermoplastic molding composition comprising aromatic polycarbonate and/or polyester carbonate and a rubber-modified graft polymer prepared by the bulk, solution or bulk-suspension polymerization process is disclosed. The composition that is characterized by its low content of lithium ions features improved hydrolytic resistance.
La présente invention concerne une composition de moulage thermoplastique antichoc. Elle comprend un polycarbonate aromatique et/ou un carbonate de polyester, ainsi qu'un polymère greffé modifié au caoutchouc obtenu par polymérisation en masse, en solution ou en suspension de la masse. Cette composition, qui se distingue par sa faible teneur en ions lithium, fait preuve d'une résistance accrue à l'hydrolyse.
