Abstract
Fumarate esters with abstractable hydrogens were found to copolymerize via photoinitiation with a variety of electron donor monomers at a relatively rapid rate under both air and nitrogen. Under air, their copolymerization rates were much faster than monofunctional or difunctional acrylates when a photoinitiator was used to initiate polymerization. Mixtures of dialkylfumarates and N-vinyl formamide (NW) had copolymerization rates faster than dialkylfumarates and N-vinyl pyrrolidone or vinyl ethers. Similar correlations were observed regardless of addition of photoinitiator. From the curing test, difunctional fumarate/NVF system showed faster curing speed than those of multifunctional acrylate with photoinitiator systems.
