Polymerization time parameters, induction time t(0) and t(50) obtained from Boltzmann sigmoidal fitting, were determined from photorheology experiments performed on diacrylate and glycol dimethacrylate suspensions with silicon dioxide, with varying photoactives concentration and in the presence of diluents. The experiments were performed at the intensity similar to 23 mW/cm(2). t(0) and t(50) are linearly proportional to reciprocal photoinitiator concentration 1/c(P), dye concentration c(D) and inhibitor concentration c(INH) as predicted by modified inhibitor exhaustion model. Further, the effect of a reactive and an inert diluent is shown. (C) 2012 Elsevier B.V. All rights reserved.
