The invention relates provides synthetic medical adhesives which exploit plant derivatives to form covalent bonds with amines and thiols on tissue surfaces.

The invention relates to a monofunctional or multifunctional acrylated or methacrylated urethane oligomer where said urethane bond is obtained without use of isocyanate and by the carbonate-amine reaction between a cyclic carbonate and a monoamine or polyamine, with subsequently the conversion of the hydroxyls in the position with respect to the urethane bond into ester-acids by reaction with a cyclic anhydride, which reaction is followed by the conversion of said acid functional groups into acrylated or methacrylated end groups by reaction with a polyepoxide compound in the presence of acrylic or methacrylic acid. The invention also relates to a preparation process. Said oligomer is used as crosslinkable binder for a functionality of at least 2 in coating, molding, leaktightness agent or sealing compositions or, if monofunctional, as macromonomer in polymerizable compositions for the production of grafted polymers.

The present invention relates to a binder system containing a resin component and a curing agent component, wherein the resin comprises at least one compound carrying at least two cyclic carbonate groups and at least one compound carrying at least two epoxy groups, and the curing agent comprises at least one multifunctional amine as well as the use of the binder system as an adhesive/sealant and the use of this adhesive/sealant.
