    摘要： Limited-play optical medium with improved shelf stability are formed from a plurality of layers, including in sequence: (a) a first substrate layer (22); (b) a data layer (25); (c) a reflective layer (24); (d) a reactive layer (23; 32,33) comprising a dye having a reduced state and an oxidized state and further comprising an oxidized form of a reducing agent effective to convert the dye from the oxidized state to the reduced state, and (e) a second substrate layer (21). The dye in the reduced state is substantially transparent to light of wavelengths used to read the optical medium, and the dye in the oxidized state absorbs light of wavelengths used to read the optical medium. The reflective metal layer is formed from a metal or metal alloy that is not significantly oxidized by the oxidized form of the reducing agent. For example, the reflective metal layer is suitably formed from silver or gold.

    摘要： A combination of a potassium salt of a perfluoroalkane sulfonate and a sodium salt of toluene sulfonic acid, preferably in the presence of an antidrip agent to provide high melt strength, act synergistically to provide flame-retarded polycarbonate compositions at low levels. Thus, a flame-retarded polycarbonate resin can be made by adding to the polycarbonate resin an effective flame-retardant amount of a potassium salt of a perfluoroalkane sulfonate and a sodium salt of toluene sulfonic acid. The two salts may be formulated in advance into an additive composition.

    摘要： Siloxane bischloroformates are prepared in a continuous process by phosgenating siloxane bisphenols in a flow reactor using a substantial excess of phosgene and sodium hydroxide. While very high levels (>95%) of conversion of the siloxane bisphenol to the corresponding siloxane bischloroformate are achieved using a flow reactor according to the method of the invention, only more modest conversion (∼90%) of the siloxane bisphenol to the corresponding siloxane bischloroformate is attained when analogous batch processes are employed. The process holds promise for use in the manufacture of silicone-containing copolycarbonates which requires high purity siloxane bischloroformate intermediates.

    摘要： Polyestercarbonates are disclosed which comprise structural units derived from at least one bisphenol derived from terpene precursors, at least one aromatic dihydroxy compound comonomer, at least one diester derived from a C1-C40 linear or branched divalent hydrocarbyl radical, and at least one carbonic acid diester. Also disclosed are methods to make the polyestercarbonates and articles derived therefrom.
