In a ruthenium-catalysed living ring-opening metathesis polymerization, one metal centre is required for each polymer chain, and this requires high catalyst loadings when aiming for short polymer chains. Now, it has been shown that a degenerative reversible chain-transfer process enables the synthesis of ring-opened metathesis polymers with controlled molecular weight, using only catalytic amounts of a ruthenium complex.
