Enabling rapid and controlled formation of polyolefins, ring-opening metathesis polymerization (ROMP) has led to ultrahigh molecular weight materials with unique optical and mechanical properties. Often in seconds to minutes, ROMP results in complete monomer consumption, even for the most sterically encumbered cases, maintaining narrow molecular weight distributions and facilitating block copolymer formation via sequential monomer addition. Although versatile, the scope of scalable polymers produced using ROMP remains limited, resulting in sparse characterization of bulk properties. This sub-group aims to systematically examine ROMP of monomers from widely accessible strained, cyclic olefins, to unveil facile processes towards polyolefins with useful bulk properties. Research consists of monomer and polymer synthesis, polymer characterization, and characterization of morphology and thermomechanical properties
