Notes:
The laser-initiated polymerization of a thiol-ene photopolymerizable system was studied. The laser was operated in single- and multiple-pulse modes to generate exotherms, which were measured in a modified differential scanning calorimeter. Arrhenius plots of the polymerization, obtained by measuring polymerization exotherms at various temperatures, showed positive and negative portions. Pseudoactivation energies for the thiol-ene polymerization increased rapidly at low conversions (〈50%) of the thiol and ene chromophores. The results were comparable to those obtained from photopolymerization of multifunctional acrylate monomers.
