Figure 3. Tensile strength and cross-link density of the irradiated PVNR films produced under various conditions: (a) effect of the mass ratio of the
photoinitiator to the coagent (R); (b) effect of the mixing time; (c) effect of the irradiation distance (x, Figure 2); (d) effect of the depth of the latex
pool (l, Figure 2); (e) effect of the irradiation time. For each study, only the factor of interest was varied while the other factors were fixed at the
following base values: the photoinitiator to coagent mass ratio of 1; a mixing time of 1 h; an irradiation distance of 45 mm; a latex pool depth of 10
mm; an irradiation time of 1 h.
