Title (EN) THERMOPLASTIC POLYCARBONATE COMPOSITIONS WITH IMPROVED MECHANICAL PROPERTIES, ARTICLES MADE THEREFROM AND METHOD OF MANUFACTURE
(FR) COMPOSITIONS DE POLYCARBONATE THERMOPLASTIQUES PRESENTANT DES PROPRIETES MECANIQUES AMELIOREES, ARTICLES FABRIQUES A PARTIR DE CES COMPOSITIONS, ET PROCEDE DE FABRICATION
Abstract:
(EN) A thermoplastic composition comprising a polycarbonate resin, a mineral filler and an acid or an acid salt, and optionally an aromatic vinyl copolymer and/ or an impact modifier, has been found to exhibit improved characteristics and less degradation than filled thermoplastic compositions without the acid or acid salt. In some embodiments the composition exhibits improved impact and ductility, as well as molecular weight' retention. An article may be formed by molding, extruding, shaping or forming such a composition to form the article.
(FR) L'invention concerne une composition thermoplastique comprenant une résine de polycarbonate, des charges minérales, et un acide ou un sel d'acide, et éventuellement un copolymère de vinyle aromatique et/ou un modificateur de résistance, ladite composition présentant des propriétés améliorées et une dégradation réduite par rapport aux compositions thermoplastiques chargées ne comprenant pas d'acide ou de sel d'acide. Selon certains modes de réalisation, la composition présente une ductilité et une résistance améliorées, ainsi qu'une meilleure rétention de la masse moléculaire. Un article peut être formé à partir d'une telle composition, par moulage, extrusion ou formage.
