Sulfole^® 120 Mercaptan for Emulsion Polymerization in Synthetic Rubber Production

Synthetic rubber producers need reliable control during polymerization to support consistent processing and repeatable product quality. In emulsion polymerization, chain transfer agents help regulate polymer chain growth, making them important for managing molecular weight in free radical polymer systems.  
Sulfole^® 120 Mercaptan, available through ChemPoint from Chevron Phillips Chemical Company, is a sulfur-based chain transfer agent primarily composed of t-dodecyl mercaptan, also known as tertiary dodecyl mercaptan or TDM. It is used in polymer and rubber production where molecular weight control is required during free radical polymerization. 

Supporting Control in Synthetic Rubber Production  

In synthetic rubber production, polymer chain length can influence processability, consistency and downstream handling. Sulfole^® 120 Mercaptan helps producers manage this part of the process by acting as a chain transfer agent during polymerization.  
This makes it relevant for manufacturers producing styrene-butadiene rubber, nitrile rubber and other polymer systems where controlled chain growth supports more consistent production. For emulsion polymerization, the value is straightforward: better control at the reaction stage helps create a stronger foundation for downstream rubber processing.  

Where this chemistry fits 

Why Producers Use TDM-Based Chain Transfer Agents  

TDM-based mercaptans are widely used where free radical polymerization requires controlled molecular weight development. By influencing chain transfer during the reaction, Sulfole^® 120 Mercaptan helps producers maintain better control over polymer characteristics without changing the overall polymerization strategy.  
For synthetic rubber and polymer producers, this supports:  
    •    Molecular weight control  
    •    More consistent polymer chain growth  
    •    Repeatable production outcomes  
    •    Improved process control during free radical polymerization  
    •    Application flexibility across rubber, styrenic, acrylic and vinyl polymer systems
