Abstract
Ultra-short light pulses from conventional nanosecond pulsed laser were not so often used for the synthesis of cross-linked polymer materials. This study of pulsed laser photopolymerization of diacrylate monomer highlights its unique dynamics compared to continuous wave photopolymerization. A model, developed to study the pulsed polymerization, accurately reproduces the staircase kinetic leading to the determination of propagation and termination rate constant dependence with monomer conversion. Inhibition was explained and well described by the model. The kinetic chain length is independent of the pulse energy and controlled by the propagation and termination rate. Application of pulsed polymerization in recording holographic phase diffraction gratings, emphasizes the influence of the medium on diffraction kinetics. This study advances knowledge of pulsed polymerization reaction for potential applications in materials synthesis.
