By carefully controlling the relative concentrations and amounts of hydroxyl and chloroformate groups present in the oligomeric polycarbonate, the method of the invention provides for the efficient preparation of polycarbonate while minimizing phosgene usage. The product polycarbonates prepared by the method of the invention are fully capped with no additional phosgene required beyond that needed to prepare the oligomeric chloroformate starting material. The method of the present invention provides polycarbonates having non-detectable levels (<5 ppm) of aromatic hydroxyl endgroups, low polydispersity, and low levels of residual monomer and endcap, thereby obviating the need for monomer and endcap recycle.Type: GrantFiled: October 16, 2002Date of Patent: August 24, 2004Assignee: General Electric CompanyInventors: James Manio Silva, Pierre-Andre Bui, Thomas Joseph Fyvie, David Michel Dardaris

Patent number: 6780813Abstract: The invention relates to an improved method of producing double-metal cyanide (DMC) catalysts for the production of polyether polyols by polyaddition of alkylene oxides to starter compounds containing active hydrogen atoms, in which the DMC catalyst dispersion is produced using a mixing nozzle, preferably a jet disperser. The DMC catalysts produced in this way have an increased activity in polyether polyol production, reduced particle size and narrower particle size distribution.Type: GrantFiled: May 30, 2002Date of Patent: August 24, 2004Assignee: Bayer AktiengesellschaftInventors: Jörg Hofmann, Bernd Klinksiek, Stephan Ehlers, Thorsten Fechtel, Franz Föhles, Pieter Ooms
