Effect of oxygen on the photopolymerization of a mixture of two dimethacrylates

In this work we study the influence of the presence of oxygen in the photocuring of a system obtained by mixing two dimethacrylates. Using an isoconversional method we have found the kinetic parameters with different atmospheres: nitrogen, air and oxygen. The inhibition effect of oxygen has been compensated by adding a greater proportion of initiator and increasing the intensity of the ultraviolet radiation. We have seen that the latter had more influence.
