tert-Dodecyl Mercaptan (t-DDM)

CAS: 25103-58-6

tert-Dodecyl mercaptan (t-DDM) is a branched-chain thiol chain transfer agent with a higher chain transfer constant than n-DDM, allowing molecular weight control at lower dosing levels. Its branched structure increases the rate of chain transfer and is preferred in emulsion polymerization of styrene-butadiene, acrylics, and nitrile rubber where low residual CTA level is critical.
