摘要： A molding composition comprising a polycarbonate resin and plating modifier was found to be suitable for preparing metal coated articles where the metal coating is deposited by an electroless process. The plating modifier in accordance with the invention is at least one member selected from the group consisting of a polyanhydride, and a monovinyl aromatic-acrylonitrile copolymer. An advantageous embodiment of the invention includes incorporating in the molding composition a flame retarding amount of a conventional flame retarding agent for polycarbonate compositions.

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： Flame resistant, reinforced thermoplastic molding compositions based on polyethylene terephthalate resins were found to have a lowered tendency to drip during burning upon the addition thereto of a sufficient amount of a particular ionic elastomer. The addition of the drip suppressant in accordance with the invention does not compromise the physical and mechanical properties of the composition.
