摘要： A composition comprising an admixture of(a) an aromatic polycarbonate of intrinsic viscosity of from about 0.35 to about 0.41 dl/g, measured in methylene chloride at about 25.degree. C., said aromatic polycarbonate chain terminated with an endcapping agent which provides the polycarbonate with improved ductility and higher Tg when compared to a paratertiary butyl phenol encapped polycarbonate of the same intrinsic viscosity;(b) a core/shell copolymer comprising a conjugated diene with a Tg of less than or equal to -10.degree. C. as the core, said core being about 50 to 90 wt. percent of the core/shell polymer, and grafted thereon a shell comprised of an alkylalkacrylate and a styrenic, the core/shell copolymer present in such quantities to render the said composition ductile in the room temperature 1/8 inch thickness Notched Izod test system under ASTM D-256, and(c) a flame retardant combination comprising a flame retardant salt, said combination in quantities sufficient to achieve a UL-94 V-0 or V-1 rating in a molded part 90 mils thick.

摘要： A polyestercarbonate copolymer blend which exhibits a glass transition temperature lower than bisphenol-A carbonate homopolymer, shows improved processability and fire-retardancy. The desired lower Tg and improved flow can be achieved by the polycondensation of a dihydric phenol and aliphatic dicarboxylic acid. The condensate is polymerized with a carbonate forming reagent. The resin is fire-retarded with a mixture of halogenated polycarbonate, potassium diphenylsulfone sulfonate and polytetrafluoroethylene.

摘要： Cyclic polycarbonate (or thiol analog) oligomer mixtures are prepared by the reaction of bishaloformates or their thio analogs, or mixtures thereof with dihydroxy or dimercapto compounds, with alkali metal hydroxides and various amines. The oligomer mixtures may be converted to polycarbonates or their thiol analogs by a method which is particularly adaptable to integration with polycarbonate processing operations. Polymerization may be conducted simultaneously with molding, extrusion and the like. The oligomer mixtures are adaptable to the preparation of filled prepregs.
