Free radical formation upon photopolymerization of oligoether acrylate composition filled by aerosil with different particle sizes

  • D. L. Starokadomsky
  • O. N. Stavinskaya


It was found that UV irradiation of a composition based on an oligoether acrylate binder and Aerosil filler gives rise to at least two types of free radicals. The presence of the filler slowed down the decay of radicals in the irradiated composition. In the completely polymerized composite, the total amount of radicals depends on the specific surface area and Aerosil concentration. The radical decay is the most intense during the first 24 h after irradiation; then the process is strongly decelerated.
