  • Publication number: 20130203912
    Abstract: In a polycarbonate resin composition containing a polycarbonate resin and a polycarbosilane compound, the use of the polycarbosilane compound modifies the surface properties of the polycarbonate resin composition without adversely affecting the intrinsic characteristics of the polycarbonate resin, such as transparency, heat resistance, and mechanical properties, e.g., impact resistance. A polycarbonate resin composition containing 100 parts by mass of a polycarbonate resin, 0.001 to 1 part by mass of a metal salt compound, and 0.005 to 5 parts by mass of a polycarbosilane compound has significantly improved flame resistance and high transparency and causes markedly reduced outgassing and mold fouling, without losing impact resistance and heat resistance.

    Abstract: The invention relates to a process that results in a fluoropolymer composition with improved chemical, thermal and color stabilities, and a reduced level of residual surfactants (both fluorosurfactants and non-fluorosurfactants. Such improvements, as indicated by total oxidizable carbon (TOC) and pellet yellowness index (YI), can be accomplished in a cost-effect manner through the use of a dewatering extruder. The dewatering extruder combines several typical unit operations into a single operation, producing solid fluoropolymer having a significantly reduced total oxidizable carbons, a lower yellowness index and minimal amounts of surfactants.

  • Publication number: 20100144939
    Abstract: A flame retardant polycarbonate resin composition comprising 100 parts by weight of a polycarbonate resin (A), 0.01 to 3 parts by weight of silsesquioxane (B), 0.005 to 1.0 part by weight of an organic metal salt compound (C) and 0.01 to 3 parts by weight of a fibril-forming type fluorinated polymer (D), wherein said silsesquioxane (B) is characterized by a specific structure (a triangular cone shape). The flame retardant polycarbonate resin composition of the present invention can achieve a high degree of flame retardance even in thin-walled molded products without generating a gas containing chlorine or bromine during combustion originating from a chlorine type or bromine type flame retardant since said flame retardant is not used. Therefore, the flame retardant polycarbonate resin composition of the present invention can ideally be used in housings and parts for electrical, electronic, ITE and the like products, and its industrial utility value is extremely high.
