Abstract
In some embodiments, the present invention is a method, comprising: a) mixing at least one polymerizable acrylic compound, a thermal initiator, a photoinitiator, and a peroxide to form a mixture, wherein the peroxide has a decomposition temperature; b) exposing the mixture to light for a sufficient first time to generate a first curing agent; and c) after exposing the mixture to light, exposing the mixture to a temperature below the decomposition temperature of the peroxide for a sufficient second time to generate a second curing agent.
