  • Antimicrobial polymeric compositions and method of treatment using them
    Patent number: 7629002
    Abstract: A polymeric antimicrobial comprising a derivative of poly(2-propenal, 2-propenoic acid) formed by reaction between a poly(2-propenal, 2-propenoic acid) and an alcohol or phenol to form protected carbonyl groups. The invention also relates to antiseptic compositions and compositions for treating gastrointestinal disease containing the polymeric antimicrobial.
    Type: Grant
    Filed: January 18, 2002
    Date of Patent: December 8, 2009
    Assignee: Chemeq Ltd.
    Inventors: Graham John Hamilton Melrose, Andrew James Huxham
  • Antimicrobial polymeric compositions
    Patent number: 6803356
    Abstract: A method for the preparation of polymers derived from acrolein and including poly(2-propenal, 2-propenoic acid), characterised in that the polymers are exposed to the presence of water, whereby such polymers exhibit increased antimicrobial activity. The polymers may be heated in the range of 40 to 150° C. Further, the polymers may be prepared in the presence of polyethylene glycols, polyols and/or alkanols.
    Type: Grant

  • Polymeric compounds and methods of formulating same
    Patent number: 6410040
    Abstract: A method for the preparation of compositions of poly(2-propenal, 2-propenoic acid) comprising the method steps of dissolving the poly(2-propenal, 2-propenoic acid) in aqueous base, adding an organic compound containing one or more hydrophobic groups, and subsequently acidifying the solution, whereby interaction between the hydrophobic groups of the organic compound and the poly(2-propenal, 2-propenoic acid) prevents precipitation of the poly(2-propenal, 2-propenoic acid) occurring at pH >5.5 and the solution is consequently stable over a broad pH range.
