Abstract

Investigations of polymerization rates in an acrylamide-based photopolymer are presented. The polymerization rate for acrylamide and methylenebisacrylamide was determined by monitoring the changes in the characteristic vibrational peaks at 1284 and 1607cm1 corresponding to the bending mode of the CH bond and CC double bonds of acrylamide and in the characteristic peak at 1629cm1 corresponding to the carbon–carbon double bond of methylenebisacrylamide using Raman spectroscopy. To study the dependence of the polymerization rate on intensity and to find the dependence parameter, the polymerization rate constant is measured at different intensities. A comparison with a commercially available photopolymer shows that the polymerization rate in this photopolymer is much faster.
