    摘要： Improved fire-retarded properties can be imparted to polycarbonate resin composition by incorporating into the polycarbonate a fire-retardant component containing a perfluoroallkane sulfonate such as potassium perfluorobutane sulfonate and a cyclic siloxane such as octaphenylcyclotetrasiloxane. The fire-retardant component is suitably added at levels to form a polycarbonate composition in which the perfluoroalkane sulfonate is present in an amount of from 0.02 to 0.1 phr relative to the composition as a whole, and the cyclic siloxane is present in an amount of at least 0.02 relative to the composition as a whole.

    摘要： The level of anhydride linkages in copolyestercarbonates is decreased by preparing the copolyestercarbonate interfacially in a two-step method from at least one dihydroxyaromatic compound and at least one dicarboxylic acid. The first step is conducted at a pH in the range of about 4.5-9.5, employing the combination of a phase transfer catalyst such as a tetraalkylammonium halide and a tertiary amine such as triethylamine. The proportion of the phase transfer catalyst is in the range of about 3-12 mole percent based on total dihydroxyaromatic compound and dicarboxylic acid employed. In the second phosgenation step, the pH is raised to at least 10 and a stoichiometric phosgene excess of at least 5% is introduced.
