    摘要： The present invention is related to polycarbonate molding compositions containing a co-precipitate of a polycarbonate resin and a fluoropolymer. This co-precipitate was found to be suitable as an additive for polycarbonate resins because it offers improved dispersibility with the resin and good flammability performance as well as aesthetic characteristics. The co-precipitate is prepared by first mixing an aqueous dispersion of a fluoropolymer with a polycarbonate solution and then precipitating both using a suitable precipitation agent. After isolation washing and drying the co-precipitate of the invention is suitable for incorporation in a polycarbonate resin optionally with known flame retarding agents. Molded parts prepared from the compositions of the invention are characterized by their improved homogeneity and flame retardance.

    摘要： A foamable thermoplastic molding composition comprising:a) an aromatic polycarbonate, andb) 0.1 to 5% by weight of a hydrate of an inorganic salt, is disclosed. The salt is inert to the polycarbonate and is capable of releasing its water of hydration only at a temperature above 100.degree. C.The composition which may optionally further contain c) up to 10% by weight of a nucleating agent, and d) up to 30% by weight of glass fibers is characterized by its good pore structure.
