Also functions as an inhibitor and shortstopping agent for acrylic and vinylic monomers.
It is a stable white solid that is soluble in a range of organic solvents and copolymerizes with other vinylic monomers.
The vinylic proton in the enamine is easily observed as a single peak at 8.81 ppm; signals at higher field belonging to the protons H-4 and 1-OH at [delta] 8.16 and 7.63 ppm, respectively, are coupled.

Synergy between the highly reactive terminal acrylate functionality and the internal vinylic structures was evident when compared to binary blends of monomeric diacrylate and poly(butadiene), and may also contribute to the efficiency of the polymeric diacrylate coagent compared to monomeric forms.
This sequence of steps--alkene binding, functionalization, and retrocycloaddition--represents an overall vinylic C-H functionalization reaction of simple olefins which does not require the use of directing groups.
Besides addition polymerization of vinylic monomers, Zhou and coworkers, after proper surface modification, performed surface-initiated ring-opening polymerizations of norbornene, lactide, and carprolactone, respectively [34-36].
