Patent ID: 7642297

Claim:
A curable, adhesive system consisting essentially of (1) at least one monomer, polymerizable by free radical initiation, selected from the group consisting of 2,2-bis[4-(3-acryloyloxy-2-hydroxypropoxy)phenyl]propane, 2,2-bis[4-(3-methacryloyloxy-2-hydroxypropoxy)phenyl]propane, diallylic ester of isophorone diisocyanate, triallyl cyanurate, triallyl isocyanurate, di- and tri-allyl ethers of trimethylolpropane, norbornene monomers, trimethylolpropane trithiol, pentaerythritol tetrathiol and their ethoxylated homologues, mixtures of said monomers, and hybrid monomers of said monomers containing chemically different polymerizable groups in one monomer; provided that when said at least one monomer is a said thiol monomer, said thiol monomer is used in combination with at least one non-thiol monomer of said acrylate monomers, methacrylate monomers, allylic monomers, norbornene monomers, mixtures of said monomers, and/or hybrid monomers of said monomers; and (2) a polymerization initiator, said adhesive system being a non-leaching system which, when in contact with liquid or liquid film present in an application in which the cured adhesive system is used, does not leach compounds that are detrimental to the application.
