  • Patent number: 6476249
    Abstract: Provided are an aromatic polycarbonate copolymer and a method for producing it. An aromatic dihydroxy compound, at least one member selected from the group consisting of polyorganosiloxanes and aliphatic polyalcohols, and a dicarbonate are prepolymerized under heat to give a polycarbonate prepolymer, and the prepolymer is polymerized in a solid or swollen solid phase in the presence of a quaternary phosphonium salt serving as a catalyst to give an aromatic polycarbonate copolymer. The remaining monomer content, the acetone soluble content (that is, the low-molecular-weight substance content) and the cyclic oligomer content of the copolymer are all reduced, and the terminal hydroxyl fraction thereof is also reduced.

  • Publication number: 20020087020
    Abstract: A method for preparing carbonates includes reacting an alkylene oxide with carbon dioxide in the presence of a catalyst and a non-protic solvent. The method further includes having the boiling point of the solvent greater than about 70° C., and removing the solvent from the reaction product. The solvent used in the various forms of the present invention can be glyme, diglyme, tetraglyme, cumene, toluene, tetrahydofuran, cyclohexanone, ethylbenzene, aromatic hydrocarbons, or ethers. The catalyst used can be a tetraalkyl ammonium halide, such as tetraethyl ammonium bromide. The alkylene oxide that can be used in the invention can include Bisphenol A, Bisphenol B, Bisphenol F, alkylene oxides that have alkyl substituent groups, alkylene oxides that have aryl substituent groups, and alkylene oxides that contain both alkyl and aryl substituent groups. An essentially solvent free carbonate can be prepared by flash removal of the solvent.
