    Abstract: The present invention relates to an adhesive composition comprising (1) at least one polyol tri(meth)acrylate monomer selected from the group consisting of ditrimethylolpropane triacrylate (DiTMPTTA), tris-(2-hydroxyethyl)-isocyanurate triacrylate (THEICTA) dipentaerythritol triacrylate (DiPETA), ethoxylated trimethylolpropane triacrylate (TMPEOTA), propoxylated trimethylolpropane triacrylate, (TMPPOTA), ethoxylated pentaerythritol triacrylate (PETEOIA), propoxylated glyceryl triacrylate (GPTA), pentaerythritol triacrylate (PETA), trimethylolpropane triacrylate (TMPTA) and modified pentaerythritol triacrylate, triethyleneglycol trimethacrylate (TIEGTMA), tetraethyleneglycol trimethacrylate (TTEGTMA), polyethyleneglycol trimethacrylate hexane trimethacrylate (HTTMA) ethoxylated bisphenol A trimethacrylate, and trimethylolpropane trimethacrylate (TMPTMA), (2) at least one polyalkylene glycol mono(meth)acrylate monomer selected from the group consisting of polypropylene glycol monomethacrylate, polyethylene glycol monomethacrylate, polyethylene glycol-polypropylene glycol monomethacrylate, polypropylene glycol monoacrylate, polyethylene glycal monoacrylate, polypropylene glycol-polytrimethylene monoacrylate, polyethylene glycol-polytetramethylene glycol monomethacrylate, methoxypolyethylene glycol monomethacrylate, yerfluoroalkylethyl-polyoxyalkylene monomethacrylate, and combinations thereof, and (3) at least one radical initiator selected from the group of initiators sensitive to UV and/or blue radiation (photoinitiator) and thermal initiators (thermoinitiator). The adhesive composition is used for assembling elements made of plastic materials, like PMMA or SAN, or inorganic materials, like glass or metals, employed for manufacturing of devices for the distribution of containment of biological substances.
