  • Composition and method for controlling cholesterol
    Patent number: 5300288
    Abstract: A nontoxic polymer comprising a backbone having a pendant groups which have sites which are capable of forming ionic bonds and sites capable of forming hydrogen bonds with respective receptive sites on the anions of conjugate acids formed by the reaction of bile acids with glycine and of bile acids with taurine, preferred polymers including polymeric amides, and pharmaceutical compositions containing the same for treatment of hypercholesterolemia.
    Type: Grant
    Filed: April 5, 1991
    Date of Patent: April 5, 1994
    Assignee: Rohm and Haas Company
    Inventor: Robert L. Albright
  • Process for removing residual monomers and oligemers from amine-containing polymers
    Patent number: 5055197
    Abstract: Treatment of water-soluble, amine-containing polymers with strong acid, cation exchange resins from aromatic copolymer crosslinked with 2-25% polyvinyl crosslinker, followed by ultrafiltration with a membrane filter having a molecular-weight cutoff, measured against the polymers to be treated, of about 10,000 to about 15,000, results in a highly effective removal of residual monomers and oligomers of less than 500 molecular weight.
