| 摘要 |
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.
