WAVE-PROPAGATION OF PHOTOPOLYMERIZATION A ND MODEL PHOTOCHEMICAL-REACTIONS IN OPTICALLY DENSE MEDIA

One-dimensional models of wave photochemical reactions proceeding in n ontransparent (absorbing) media were studied by methods of theoretical analysis and computer simulation. The laws of propagation of the conv ersion profile (reaction front) were established for various values of the kinetic and optical parameters of a system, A nonideal propagatio n of light was taken into account by introducing an appropriate instru mental transmission function, The proposed method of experimental data processing was used for a quantitative description of the photooxidat ion of 9,10-diphenylanthracene in a polymeric matrix. This approach ca n be used for analysis of the laws of a wave radical photopolymerizati on, in which the monomer conversion profile coincides with that of the photoinitiator conversion.
