Abstract
A composition is prepared of a liquid vinyl monomer, a UV-activated photo-initiator, a thermal initiator, and an accelerator. The composition also preferably contains a free-radical scavenger and a vinyl oligomer. Upon exposure to ultraviolet light the photo-initiator initiates polymerization in the surface layer thereby generating sufficient heat to activate the thermal initiator and cause the polymerization to proceed throughout the bulk of the monomer.
