Abstract: The present invention relates to a cyanoacrylate-based bio-adhesive composition, and aims to provide a cyanoacrylate-based bio-adhesive composition having an excellent biodegradability and anti-bacterial effect. The present invention provides a cyanoacrylate-based bio-adhesive composition having an enhanced biodegradability by using, as a thickening agent, poly octyl cyanoacrylate generated as a byproduct when preparing octyl cyanoacrylate, and having an excellent anti-bacterial effect by using 3,5-diiodo-4-pyridone-1-acetic acid as an anion stabilizer.

Abstract: The disclosure relates to a suture manufactured using poly octyl cyanoacrylate, and a method for manufacturing same. The disclosure provides a method for manufacturing a suture, and a suture prepared using the method, the method comprising: a step for preparing octyl cyanoacetate by reacting cyanoacetic acid and octane alcohol by 1:1 equivalence ratio under the existence of a solvent; a step for reacting the octyl cyanoacetate and paraformaldehyde by 1:1 equivalence ratio under the existence of a solvent; a step for isolating and refining octyl cyanoacrylate after removing the solvent when the reaction is completed; a step for collecting poly octyl cyanoacrylate from the byproduct left from refining octyl cyanoacrylate; and a step for manufacturing a suture by a braid process after manufacturing a thread by melt spinning and extrusion molding the collected poly octyl cyanoacrylate.
