Abstract
Isocyanatoethyl methacrylate (IEM)©is a difunctional monomer with an aliphatic isocyanate functionality and a vinyl polymerizable double bond. Either end of the molecule can be reacted first, leaving the other functionality for latent reaction. The isocyanate group reacts with active hydrogen compounds at rates of reaction similar to other commercial aliphatic isocyanates. The methacrylate functionality allows copolymerization with other common vinyl monomers at reaction rates similar to methyl methacrylate. Applications for IEM fall into three categories: polyisocyanates made by polymerizing the methacrylate group, vinyl functionalized resins made by reacting the isocyanate group with polyfunctional molecules and polymerizable derivatives made by reacting the isocyanate group with monofunctional reagents. In this last application category, the blocked-IEM derivatives allow the benefits of IEM to be extended into water-based and one-component urethane systems. The majority of applications reported to date utilize IEM as a latent crosslinker or graft site to make resins suitable for coatings or adhesives.
