  • Thermal separation method for mixed polymers
    Patent number: 6683153
    Abstract: A method for separating technical and biological polymers by generating two liquid phases using an added gas or an adjusted temperature. The separated polymers are obtained in solution with a high degree of purity. Complete separation can be achieved by subsequently performing liquid chromatography during which the corresponding trace component irreversibly adheres to the column while the other trace component is not retarded.
