As the isocyan group is polymerized further, diphenyl carbondiimine may be formed, further polymerization of which forms a nitrogen-containing polycyclic aromatic compound.
Results indicate interestingly that the double bond of GMA polymerized with polystyryl carbanion and the molar ratio of epoxy end group and polystyrene oligomer can be adjusted.
But because it holds onto it's electrons so tightly, and is so satisfied in this polymerized chain, the electrons are unavailable for even minimal interactions with any other molecules.
I started to try to make things that might polymerize with metal ions into structures in the middle 80s and the whole thing started to look very promising, but it really was very common sense.
