    摘要： The present invention provides a polycarbonate resin produced by the continuous interfacial process characterized in that after alkaline hydrolysis with sodium hydroxide, the polycarbonate resin contains an amount of 0.01 to 150 ppm of carbamate compounds according to formula (1) said amount measured by high pressure liquid chromatography, wherein R1 and R2 independently of one another denote hydrogen or C1-C12-alkyl, or together denote C4-C12-alkylidene, and R3 and R4 independently of one another denote hydrogen. C1-C12-alkyl or phenyl, or together with the carbon atom to which they are bonded form cyclohexyl or trimethylcyclohexyl, the process comprising phosgene reacting with at least one bisphenol at 8 to 17% molar excess of phosgene relative to the bisphenol.

    摘要： A method for reducing the content of fluorescent particles in polycarbonate is disclosed. The method entails bringing into contact polycarbonate, in the melt or in solution, with aluminosilicate at a temperature and for a time calculated to obtain polycarbonate having fluorescent particles content of 0 to 5 counts/g of polycarbonate. In a preferred embodiment the polycarbonate is passed through a column packed with zeolite.
