Ring opening metathesis polymerization mechanism
Ring-opening metathesis polymerization (romp) offers good control over dispersity, but the requirement of one initiator per chain can be expensive and problematic for purification now, a reversible cyclohexenyl-containing chain-transfer agent is described, thus allowing a catalytic living romp process to produce narrow dispersity polymers.
