1,5-bis(4-methoxyphenyl)-3-methyl-pentaaza-1,4-diene, 1,5-bisphenyl-3-(2`-oxyethyl)-pentaaza-1,4-diene and 1,5-bisphenyl-3-methyl-pentaaza-1,4-diene were studied by differential scanning photocalorimetry (DPC) and dilatometry methods as photoinitiators of radical polymerization of vinyl monomers. Photoinitiation abilities of the compounds investigated were compared with those of industrial photoinitiator IRGACURE 1 700. Pentaazadienes exibit a high initiation capacity, the activation energy of polymerization process in the presence of pentaazadiene compounds being lower than that for IRGACURE 1700. An increase of the initiator concentration results in a decrease of the rate of the process. The phenomenon can be explained by autoinhibition.
