medical applications

Cyanoacrylate polymer foams can be obtained by blending cyanoacrylate monomer with an appropriate solvent and a polymerization initiator. Foaming takes place in seconds at room temperature. Various monomers, solvents and initiators were tested and best performance compositions and ratios were determined. The resultant foams are lightweight and can occupy volume up to 30 times that of the original cyanoacrylate monomer. The onset time and temperature of foaming can be regulated in wide ranges. Odourless foaming compositions were obtained.

Currently, new formulations of -cyanoacrylic tissue adhesives, are being studied for the repair of soft and hard tissue in order to improve properties such as: biodegradability, biocompatibility bone flexibility (in the soft tissue applications) and ease of handling. This paper presents a review of scientific literature related to new formulations of -cyanoacrylic adhesives and medical applications.
