Average bulk polymerization rates of various acrylates (10–50 % conversion) versus their kp/kct ratios with butyl mercaptopropionate. The polymerization rates have been normalized with respect to initial double bond concentration of acrylates. Polymerization conditions: light intensity = 5 mW/cm2, initiator concentration = 0.1 wt% DMPA, room temperature, weight ratios of acrylate/thiol ranging from 70/30 to 50/50.
