  • Branched polyamines and formulations thereof for use in medical devices
    Patent number: 8450529
    Abstract: The present disclosure provides for the synthesis of branched polyamines. In embodiments, branched polyamines may be formed by reacting a branched polyol with a nitroaryl carboxylic acid to form a nitrobenzoyl ester which, in turn, may then be subjected to a hydrogenating step to form the branched polyamine. The resulting branched polyamine may then be reacted with another hydrogel precursor to form a hydrogel.

  • Adhesive formulations
    Patent number: 8349987
    Abstract: The disclosure relates to biocompatible components useful for forming compositions for use as medical/surgical synthetic adhesives and sealants. Biocompatible components of the present disclosure may include a polymeric polyol core, which may be treated with a nitroaryl compound to form a nitro ester. The resulting nitro ester groups may be reduced to form amino groups which, in turn, may be treated to form isocyanate groups. The resulting isocyanate may then be reacted with a second component to form adhesive and/or sealant compositions.
