Abstract

The photoinitiated polymerization of three bisphenol-A-based dimethacrylates is studied. The polymerization rate of the dimethacrylate increases with temperature up to 160-degrees-C. Above this temperature depropagation starts to dominate the polymerization and the rate approaches zero above 210-degrees-C. In the case of the diacrylates three temperature regions are distinguished. Below 90-degrees-C the polymerization rate increases with temperature. Between 90 and 145-degrees-C chain transfer suppresses the autoacceleration which results in a decreasing polymerization rate with increasing temperature. Above 145-degrees-C depropagation causes an additional rate decrease.
