Abstract
Frontal polymerization is a process in which a localized reaction zone propagates through monomer or monomers, leaving polymer in its wake, by the coupling of thermal transport and the Arrhenius dependence of the reaction rate of an exothermic polymerization. One-pot formulations with long shelf lives can be created that will cure rapidly when a front is started and require less energy than traditional batch curing. Frontal polymerization can be used to create composites from acrylates and inorganic fillers for use in rapid repair and for sculpture without using an oven or kiln. Radical-induced cationic polymerization and frontal ring-opening metathesis polymerization are effective methods to create fiber-reinforced composites with comparable mechanical properties to batch cured epoxy systems.
