Abstract

The polymerization behavior of acrylic monomers in the light-cured composite resins and the stability of residual radicals were investigated. The monomer conversion and radical concentration were determined by ESR and IR spectroscopies under various conditions. Slow polymerization proceeded even in the dark by residual radicals, which served post curing of the resins. A decrease in monomer consumption was observed at the surface due to an inhibition effect of oxygen on the photoinitiation process.
