Abstract

A previously reported polymerizable benzophenone photosensitizer, 2-methacryloxyethyl 4-benzoylbenzoate (MEBB), was synthesized and characterized. The photopolymerization kinetics of methyl alpha-hydroxymethylacrylate (MHMA) and 1,6-hexanediol diacrylate (HDDA) initiated with MEBB or benzophenone (BP) in the presence or absence of amine co-initiators were determined by photo-differential scanning calorimetry. The results indicate that benzophenone with a p-carbonyl substitutent is more efficient in photoinitiation when compared to the non-substituted benzophenone analogue. The final monomer conversions in the presence of amine co-initiators are slightly higher than without them. (c) 2005 Society of Chemical Industry.
