Abstract: An adhesive composition is provided including one or more polymerizable cyanoacrylate monomers and boron trifluoride as a stabilizer or complexing agent. The adhesive composition may also include or be used with a decomplexing agent, particularly one or more quaternary ammonium fluoride salts or one or more quaternary ammonium ether salts. A polymerization initiator or accelerator may also be used. The viscosity of the adhesive composition may be controlled by addition of a thickening agent which may be a polymer or copolymer catalyzed by a boron trifluoride complex or compound. Methods for the application of the adhesive compositions to living tissue are also provided.

Abstract: 2-Aryl- and 2-alkyl-2-oxazolines have been polymerized to poly-(N-aroyl)aziridines and poly(N-acyl)aziridines, respectively, in the presence of boron trifluoride. The polymers obtained were glassy, light yellow resins with molecular weights ranging from 3500 to 7500 (35–50 oxazoline units per chain). The polymerization rates have been determined for several of these monomers. A polymerization mechanism is proposed.
