Abstract
A method of light-promoted frontal ring-opening metathesis polymerization includes providing a monomer solution including dicyclopentadiene, a ruthenium-based catalyst and a phosphite inhibitor, and exposing the monomer solution to ultraviolet light having a wavelength in a range from 315 nm to 400 nm, thereby initiating an exothermic polymerization reaction and generating a self-propagating polymerization front. The polymerization front moves through the monomer solution and polymerizes the dicyclopentadiene.
