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 multifunctional amine or multifunctional polyol core, with isocyanate and/or polyalkylene oxide arms, which may optionally be capped with electrophilic or nucleophilic groups. These biocompatible components may, in embodiments, be combined with optional cross linkers to form adhesive and/or sealant compositions.
