For large scale industrial processing the use of water as green solvent, and the application of energy efficient process techniques is of high interest for polymer synthesis. Frontal polymerization in aqueous formulations, fits perfectly both requirements. In frontal polymerization a one time energy input is used to start a process in which the heat of the reaction induces a polymerization in the surrounding monomer, leading to a self propagating localized reaction zone through the whole reaction vessel. Bubble formation due to solvent boiling or initiator decomposition leads to numerous drawbacks like uncontrollable heat loss, porous polymer samples, expansion of the material and in the case of initiation by UV light, diffuse scattering of the light beam. Within this work a new thermal initiator has been synthesized and applied in UV initiated frontal polymerization, allowing us to report the first completely bubble free thermal front reaction in water.
