The effect of intramolecular hydroxyls on the electron beam polymerization and photopolymerization of monoacrylate monomers has been studied. In both polymerization methods, the rate of polymerization of monoacrylate monomers containing a hydroxyl was several times faster than those without hydroxyls. This can be partly explained by the higher viscosity of the hydroxyl containing monomer, resulting in a decrease in the termination rate constant to increase the polymerization rate. In electron beam polymerization, an increase in initiating species by the generation of radicals from the hydroxyls can also accelerate the polymerization.
