Super glue, structure

Polymers are also used as sutures. Fighters and other athletes have used poly(alpha-cyanoacrylates), super glues, to quickly stop blood flow in surface cuts. Today, super glue is also used for, in place of or along with, more traditional polymeric suture threads for selected surface wounds, internal surgery, and retinal and corneal surgery. The alpha-cyanoacrylate polymers (structure 19.22) undergo anionic polymerization in the presence of water. More about sutures is explained in Section 19.6. 

A common trait of simple organic compounds is to have Lewis structures where all atoms have a formal charge of zero. Consider the following incomplete Lewis structure for an organic compound called methyl cyanoacrylate, the main ingredient in Super Glue. 

Therefore, this alkene should be readily polymerized by base, just like super glue (Section 12-15). Polymer structure will be... 

Super glue is an addition polymer of the following monomer. Draw a structural formula for a three-unit section of super glue. 

Cyanoacrylates (H2C=C(CN)-C00R) are also called super glues . The structure of the side chain (R)... 

Super Glue is a polymer formed via an anionic polymerization of methyl cyanoacrylate, CH2=(C=N)C02CH3. Predict the structure of this glue. 

Methyl methacrylate, the monomer used in super glue, polymerizes by an anionic mechanism. Its structure is typical of such monomers and consists of two electron-withdrawing groups that facilitate reactions with relatively weak nucleophiles such as the —OH groups found in cellulose through the formation of a strong polymer...
