  • Alkylated amine polymers
    Patent number: 5693675
    Abstract: The invention relates to alkylated amine polymers and a method for removing bile salts from a patient that includes administering to the patient a therapeutically effective amount of product produced by a process comprising alkylating one or more crosslinked amine polymers, salts or copolymers thereof with at least one alkylating agent. The reaction product is characterized in that: (i) at least some of the nitrogen atoms are unreacted with alkylating agent; and (ii) less than 10 mol % of the nitrogen atoms in the polymer react with the alkylating agent to form quaternary ammonium units.
    Type: Grant
    Filed: June 5, 1995
