Parameters of the kinetic model were obtained from the literature (the subscript 1 indicates IBoMA and the subscript 2 represents DEGDMA).
In the case of IBoMA the fitting was performed using the same parameters previously reported in the literature : [V.sub.f,m1]* = 0.0710, [V.sub.f,p1]* = 0.0522 and log [k.sub.t0] = 21.63 ([k.sub.t0] in L/mol/s).
This decrease begins at much lower conversions in the case of DEGDMA than in the case of IBoMA.
This decrease in [k.sub.t0] when adding small amounts of DEGDMA to IBoMA, is the main factor leading to the observed increase in the polymerization rate (Figs.
For the polymerization of DEGDMA its value is about 50 times less than the one for the polymerization of IBoMA.
For IBoMA, reaction-diffusion becomes a significant termination mechanism only at intermediate conversions.
For pure IBoMA this is mainly determined by the decrease in the initiator efficiency.
On the one hand, there is an increase in the concentration of radicals produced by the decrease of the overall termination rate and the increase in the initial concentration of initiator (a molar ratio of 1.876 X [10.sup.-2] moles per mol of C=C groups was selected for every formulation leading to mass fractions of 2 wt% for IBoMA and 3.61 wt% for DEGDMA).
