  • Cross-linked quaternary ammonium derivatives of poly(N,N-dialkylallyl) ammonium polymers
    Patent number: 5589166
    Abstract: The invention concerns novel cross-linked poly(N,N-dialkylallyl)ammonium polymer materials containing quaternary propylammonium structural units which are effective in lowering elevated plasma levels of low density lipoproteins and lipoid components thereof, such as cholesterol, and which are of value in the treatment of conditions in which such elevated plasma levels are associated, for example, various vascular diseases. The invention also provides methods for the manufacture of the polymer materials and various intermediates for use in such manufacture.
    Type: Grant
    Filed: June 5, 1995
    Date of Patent: December 31, 1996
    Assignee: Zeneca Limited
    Inventors: Fergus McTaggart, Denis Pemberton, Graham J. Smith
