CyanoAcrylate Polymerisation

[LoungeLizard]

I am looking at the above reaction as it occurs in the glueing action of super glue.

There is one N per molecule of monomer, am I right in thinking there is also only one N per molecule of polymer? 

As far as I can tell, the repeating part of the polymer consists only of Cs and Hs.  Is this correct?  If so what happens to the excess Ns after polymerisation?

Cyanoacrylates are addition polymers. The monomer contains a carbon-carbon double bond. Nothing is "lost" during polymerisation, The nitrogen containing side cahins are still there. The repeating unit is similar to the monomer except that the original double bond becomes a single bond.

sorry this is a little late. The reaction is initiated by water via a micheal type addition to the double bond. The monomer is prepared finally by the depolymerisation of the polymer at high temps. I assume the monomer is prepared via the reduction of an amine or CN attack of vinyl alcohol.
