<br/>Ring-opening metathesis polymerization (ROMP) is an incredibly powerful method for preparation of a diverse range of polymers and materials. Traditionally, ROMP is mediated by well-defined transition metal complexes. We have explored the possibility of electro-mediated ROMP that can circumvent reliance on metal-based reagents. Our method has been adapted to enable metal-free ROMP via photoredox-mediated oxidation of electron rich vinyl ether initiators. Moreover, the ability to use benign visible light to drive the polymerization provides operational advantages and temporal control over polymer growth. We will present our most recent developments, which have targeted an expanded scope of monomers, systems capable of bulk curing and crosslinking, block copolymer synthesis, and application of electrochemical mediators to control polymer molecular weight.<br/>
