  • Patent number: 6821059
    Abstract: A polyurethane-forming reaction mixture characterized by its ability to be adjusted with respect to its viscosity in response to changing temperature and humidity conditions is achieved with a mixture that includes a liquid polyisocyanate having an isocyanate group content of at least 10% by weight, an isocyanate-reactive component which includes at least one high molecular weight polyol, a urethane catalyst and from 0.2 to 5 parts by weight per 100 parts by weight of isocyanate reactive component of a viscosity adjusting component. The viscosity adjusting component is preferably a diamine, a polyamine and/or an amine-terminated polyol.

  • Patent number: 6822068
    Abstract: This invention relates to a process for the preparation of highly-branched polyols by polymerisation of glycidol in the presence of a hydrogen-active starter compound with basic catalysis, wherein glycidol is added in dilute solution and the solvent used for the dilution is continuously distilled off. The polyols thus prepared are colorless, contain as the core unit solely the starter compound used and have polydispersities of less than 1.7. The present invention also relates to polyols that comprise the reaction product of the polyols based on glycidol with one or more expoxide monomers. This invention also relates to a process for the preparation of these polyols.

  • Publication number: 20040229330
    Abstract: The present invention provides a method for high efficiency capture and purification of a tagged protein from a protein preparation, especially a tagged protein of low quantity. The method comprises a first concentration step, concentrating a target tagged protein by a negatively charged capture support; and a second purification step, purifying the tagged protein by a tag-specific affinity support. The method is especially useful for capturing and purifying tagged protein of low quantity. The present invention also provides a kit for the capture and purification of the tagged protein.
