Two different groups of methacrylates based on Irgacure 2959, Irgacure 184, benzophenone and acetophenone were synthesized.
Photopolymerization efficiency of the initiators was determined using photo-DSC.
The effect of polymerizable group structure on photoinitiation efficiency was found to be minimal for fast polymerizing systems.
Irgacure 2959, Irgacure 184 and BP-based MPIs showed similar or increased activity compared to their commercial analogs.
